cc4b32ad4a fix: complete unified resources WebSocket integration
Backend:
- Call SetMonitor after router creation to inject resource store
- Add debug logging for resource population and broadcast

Frontend:
- Add resources array to WebSocket store initial state
- Handle resources in WebSocket message processing
- Use reconcile for efficient state updates

The unified resources are now properly:
1. Populated from StateSnapshot on each broadcast cycle
2. Converted to frontend format (ResourceFrontend)
3. Included in WebSocket state messages
4. Received and stored in frontend state
5. Consumed by migrated route components

Console now shows '[DashboardView] Using unified resources: VMs: X'
confirming the migration is working end-to-end.

cac109b497 fix: Populate resources on-demand when /api/resources is called
The Resources page was showing 0 resources because the store was only
populated when /api/state was called (from the dashboard). Now the
resources are populated on-demand when /api/resources is accessed.

Changes:
- Added StateProvider interface to ResourceHandlers
- SetStateProvider() method for injecting the monitor
- HandleGetResources now calls PopulateFromSnapshot before querying
- Router injects monitor as state provider during SetMonitor()

This ensures the /resources page works even when accessed directly
without visiting the main dashboard first.

93223d8283 Add refresh-cluster button to detect new Proxmox cluster members
When new nodes are added to a Proxmox cluster after Pulse was
initially configured, they weren't showing up in Settings. The
existing "Refresh" button only triggered network discovery, not
cluster membership re-detection.

Changes:
- Add POST /api/config/nodes/{id}/refresh-cluster endpoint
- Add "Refresh" button in cluster node panel in Settings
- Re-detect cluster membership and update stored endpoints

073d5ffa55 fix: Use --ctid instead of --standalone --http-mode in quick-setup command
The quick-setup command for temperature monitoring was generating
--standalone --http-mode which is meant for Docker deployments. This
confused users trying to set up multi-server Proxmox monitoring.

Now uses --ctid which works for both local and remote Proxmox hosts.
The installer detects when the container doesn't exist locally and
installs in "host monitoring only" mode automatically.

If we can determine the actual CTID from the host proxy summary,
we use it; otherwise we show <PULSE_CTID> for the user to replace.

6b84b9a2bf Add PULSE_AUTH_HIDE_LOCAL_LOGIN option to hide password form
Implements #750 - allows hiding the username/password login form when
using OIDC SSO to avoid user confusion, while maintaining security.

- Added HideLocalLogin config option (env: PULSE_AUTH_HIDE_LOCAL_LOGIN)
- Exposed hideLocalLogin in /api/security/status endpoint
- Updated Login.tsx to conditionally hide local login form
- Added escape hatch via ?show_local=true URL parameter

This approach avoids the security and upgrade issues that led to
DISABLE_AUTH being removed (see #707, #678), while solving the UX
problem of users being confused by multiple login options.

Introduced sync.RWMutex to protect concurrent access to configuration
fields (AuthUser, AuthPass, APITokens) that are modified by the
ConfigWatcher at runtime.

- Added global config.Mu RWMutex in internal/config/config.go
- Protected config updates in ConfigWatcher.reloadConfig() and reloadAPITokens()
- Protected config reads in CheckAuth and all API token handlers
- Protected Router.SetConfig() during full config reloads

This prevents race conditions when .env file changes trigger config
reloads while authentication handlers are reading the same fields.

844c895521 WIP: Fix temperature proxy registration persistence (incomplete)
This commit contains multiple fixes for temperature proxy registration,
but the core issue remains unresolved.

## What's Fixed:
1. Added config pointer and reloadFunc to TemperatureProxyHandlers
2. Added SetConfig method to keep handler in sync with router config changes
3. Added config reload after registration to prevent monitor from overwriting
4. Fixed installer port conflict detection and duplicate YAML key issues
5. Added comprehensive debug logging throughout registration flow

## What's Still Broken:
The TemperatureProxyURL, TemperatureProxyToken, and TemperatureProxyControlToken
fields are NOT persisting to nodes.enc after SaveNodesConfig is called.

Debug logs confirm:
- HandleRegister correctly updates nodesConfig.PVEInstances[matchedIndex]
- The correct data is passed to SaveNodesConfig (verified in logs)
- SaveNodesConfig completes without errors
- Config reload executes successfully
- BUT after Pulse restart, the fields are empty when loaded from disk

The bug is in SaveNodesConfig serialization or file writing logic itself.

4fbb118072 Add PULSE_LXC_CTID env override for LXC CTID detection
Modern Proxmox LXC containers (cgroup v2 + systemd) don't expose the CTID
inside the guest namespace. The auto-detection in DetectLXCCTID() works
for older LXC setups and when hostname is numeric, but fails for most
production containers where users set custom hostnames.

Changes:
- Added PULSE_LXC_CTID environment variable override in router.go:490-495
- Graceful fallback: auto-detect first, then check env var, then show placeholder
- UI already handles missing CTID by showing "pct exec <ctid>" placeholder

This provides a robust solution for thousands of users:
- Stock Proxmox LXC: Shows `pct exec <ctid>` placeholder (user substitutes manually)
- Custom hostname containers: Can set PULSE_LXC_CTID=171 in compose/systemd
- Numeric hostname containers: Auto-detected (backwards compatible)

639635a84b Add Docker container name auto-detection to bootstrap UI
- Added DetectDockerContainerName() to detect container name from hostname

- Updated FirstRunSetup to show actual container name when detected:
  * Before: 'docker exec <container-name> cat /data/.bootstrap_token'
  * After: 'docker exec pulse cat /data/.bootstrap_token'

This reduces friction for users - no need to look up the container name.
Works when Docker container is named (--name flag), falls back to
placeholder for auto-generated container IDs.

ae0481c982 Improve bootstrap token UX with smart environment detection
- Added DetectLXCCTID() to internal/system/container.go to detect Proxmox container ID
- Extended /api/security/status to expose inContainer and lxcCtid fields
- Updated FirstRunSetup to show most relevant command based on detected environment:
  * LXC with CTID: Shows 'pct exec 171 -- cat /etc/pulse/.bootstrap_token'
  * Docker: Shows 'docker exec <container-name> cat /data/.bootstrap_token'
  * Bare metal: Shows 'cat /etc/pulse/.bootstrap_token'
- Collapsed alternative methods behind 'Show other retrieval methods' button

This addresses user feedback that showing all options was overwhelming.
Now users see the command most likely to work for their setup first,
with alternatives hidden but still accessible.

a2b8940873 Add Pulse API endpoints for temperature proxy registration
Implements REST API endpoints to enable automatic registration of
temperature proxies during sensor-proxy installation.

API endpoints:
- POST /api/temperature-proxy/register
  - Accepts: hostname, proxy_url
  - Returns: authentication token
  - Finds matching PVE instance and configures proxy URL/token
  - No authentication required (called during installation)

- DELETE /api/temperature-proxy/unregister?hostname=X
  - Removes proxy configuration from PVE instance
  - Requires admin authentication

Implementation:
- Uses config.ConfigPersistence for loading/saving nodes.enc
- Matches PVE instances by hostname in Host field or ClusterEndpoints
- Generates cryptographically secure random tokens (32 bytes, base64)
- Atomic config updates (load → modify → save)

Next step: Update install-sensor-proxy.sh to call registration API

56a7579c99 Add Remember Me feature with sliding session expiration (Related to #707)
Implements a "Remember Me" option that allows users to stay logged in
for 30 days instead of the default 24 hours. This addresses the pain
point of frequent re-authentication in LAN-only environments while
maintaining authentication security.

Backend changes:
- Add rememberMe field to login request handling
- Support variable session durations (24h default, 30d with Remember Me)
- Implement sliding session expiration that extends sessions on each
  authenticated request using the original duration
- Store OriginalDuration in session data for proper sliding window
- Update session cookie MaxAge to match session duration

Frontend changes:
- Add "Remember Me for 30 days" checkbox to login form
- Pass rememberMe flag in login request
- Improve UI with clear duration indication

Key features:
- Sessions extend automatically on each request (sliding window)
- Original duration preserved across session extension
- Backward compatible with existing sessions (legacy sessions work)
- Sessions persist across server restarts

This provides a better user experience for LAN deployments without
compromising security by completely disabling authentication.

946e2e455f Security: Fix path traversal vulnerability in host-agent download endpoint
CRITICAL SECURITY FIX: The /download/pulse-host-agent endpoint was directly
concatenating user-supplied platform and arch query parameters into file paths
without validation, allowing path traversal attacks.

An attacker could request:
  /download/pulse-host-agent?platform=../../etc/passwd
to read arbitrary files from the container filesystem.

Fix: Add input validation to only allow alphanumeric characters and hyphens
in platform/arch parameters before using them in file paths.

48f8473200 Fix router to allow frontend pages without authentication
When a request for /login (or any other frontend route) comes in without
proper Accept headers (like from curl or some browsers), the server was
returning 'Authentication required' text instead of serving the frontend HTML.

This is because the router was checking authentication before serving ANY
non-API route, including frontend pages like /login, /dashboard, etc.

The fix: Frontend routes should always be served without backend auth checks.
The authentication logic runs in the frontend JavaScript after the page loads.

Backend auth should only block:
- API endpoints (/api/*)
- WebSocket connections (/ws*, /socket.io/*)
- Download endpoints (/download/*)
- Special scripts (/install-*.sh, etc.)

All other routes are frontend pages that need to be served to everyone so
the login page can load and handle auth in the browser.

This fixes the integration tests where Playwright couldn't see the login
form because the server was rejecting the /login request before serving HTML.

Refactor update service to eliminate polling and race conditions
This commit implements a comprehensive refactoring of the update system
to address race conditions, redundant polling, and rate limiting issues.

Backend changes:
- Add job queue system to ensure only ONE update runs at a time
- Implement Server-Sent Events (SSE) for real-time update progress
- Add rate limiting to /api/updates/status (5-second minimum per client)
- Create SSE broadcaster for push-based status updates
- Integrate job queue with update manager for atomic operations
- Add comprehensive unit tests for queue and SSE components

Frontend changes:
- Update UpdateProgressModal to use SSE as primary mechanism
- Implement automatic fallback to polling when SSE unavailable
- Maintain backward compatibility with existing update flow
- Clean up SSE connections on component unmount

API changes:
- Add new endpoint: GET /api/updates/stream (SSE)
- Enhance /api/updates/status with client-based rate limiting
- Return cached status with appropriate headers when rate limited

Benefits:
- Eliminates 429 rate limit errors during updates
- Only one update job can run at a time (prevents race conditions)
- Real-time updates via SSE reduce unnecessary polling
- Graceful degradation to polling when SSE unavailable
- Better resource utilization and reduced server load

Testing:
- All existing tests pass
- New unit tests for queue and SSE functionality
- Integration tests verify complete update flow

df185985eb Fix bootstrap token path display for Docker deployments (related to #680)
The first-run setup UI was displaying incorrect bootstrap token paths for
Docker deployments. It showed `/etc/pulse/.bootstrap_token` regardless of
deployment type, but Docker containers use `/data/.bootstrap_token` by
default (via PULSE_DATA_DIR env var).

Changes:
- Extended `/api/security/status` endpoint to include `bootstrapTokenPath`
  and `isDocker` fields when a bootstrap token is active
- Updated FirstRunSetup component to fetch and display the correct path
  dynamically based on actual deployment configuration
- For Docker deployments, UI now shows both `docker exec` command and
  in-container command
- Falls back to showing both standard and Docker paths if API data
  unavailable (backward compatibility)

This fix ensures users always see the correct command for their specific
deployment, including custom PULSE_DATA_DIR configurations.

1b221cca71 feat: Add configurable allowlist for webhook private IP targets (addresses #673)
Allow homelab users to send webhooks to internal services while maintaining security defaults.

Changes:
- Add webhookAllowedPrivateCIDRs field to SystemSettings (persistent config)
- Implement CIDR parsing and validation in NotificationManager
- Convert ValidateWebhookURL to instance method to access allowlist
- Add UI controls in System Settings for configuring trusted CIDR ranges
- Maintain strict security by default (block all private IPs)
- Keep localhost, link-local, and cloud metadata services blocked regardless of allowlist
- Re-validate on both config save and webhook delivery (DNS rebinding protection)
- Add comprehensive tests for CIDR parsing and IP matching

Backend:
- UpdateAllowedPrivateCIDRs() parses comma-separated CIDRs with validation
- Support for bare IPs (auto-converts to /32 or /128)
- Thread-safe allowlist updates with RWMutex
- Logging when allowlist is updated or used
- Validation errors prevent invalid CIDRs from being saved

Frontend:
- New "Webhook Security" section in System Settings
- Input field with examples and helpful placeholder text
- Real-time unsaved changes tracking
- Loads and saves allowlist via system settings API

Security:
- Default behavior unchanged (all private IPs blocked)
- Explicit opt-in required via configuration
- Localhost (127/8) always blocked
- Link-local (169.254/16) always blocked
- Cloud metadata services always blocked
- DNS resolution checked at both save and send time

Testing:
- Tests for CIDR parsing (valid/invalid inputs)
- Tests for IP allowlist matching

16c29463f9 Fix Windows host agent installer reliability (related to #654)
The download endpoint had a dangerous fallback that silently served the
wrong binary when the requested platform/arch combination was missing.
If a Docker image shipped without Windows binaries, the installer would
receive a Linux ELF instead of a Windows PE, causing ERROR_BAD_EXE_FORMAT.

Changes:
- Download handler now operates in strict mode when platform+arch are
  specified, returning 404 instead of serving mismatched binaries
- PowerShell installer validates PE header (MZ signature)
- PowerShell installer verifies PE machine type matches requested arch
- PowerShell installer fetches and verifies SHA256 checksums
- PowerShell installer shows diagnostic info: OS arch, download URL,
  file size for better troubleshooting

This prevents silent failures and provides clear error messages when
binaries are missing or corrupted.
