rcourtman 1a78dcbba2 Fix guest agent disk data regression on Proxmox 8.3+
Related to #630

Proxmox 8.3+ changed the VM status API to return the `agent` field as an
object ({"enabled":1,"available":1}) instead of an integer (0 or 1). This
caused Pulse to incorrectly treat VMs as having no guest agent, resulting
in missing disk usage data (disk:-1) even when the guest agent was running
and functional.

The issue manifested as:
- VMs showing "Guest details unavailable" or missing disk data
- Pulse logs showing no "Guest agent enabled, querying filesystem info" messages
- `pvesh get /nodes/<node>/qemu/<vmid>/agent/get-fsinfo` working correctly
  from the command line, confirming the agent was functional

Root cause:
The VMStatus struct defined `Agent` as an int field. When Proxmox 8.3+ sent
the new object format, JSON unmarshaling silently left the field at zero,
causing Pulse to skip all guest agent queries.

Changes:
- Created VMAgentField type with custom UnmarshalJSON to handle both formats:
  * Legacy (Proxmox <8.3): integer (0 or 1)
  * Modern (Proxmox 8.3+): object {"enabled":N,"available":N}
- Updated VMStatus.Agent from `int` to `VMAgentField`
- Updated all references to `detailedStatus.Agent` to use `.Agent.Value`
- The unmarshaler prioritizes the "available" field over "enabled" to ensure
  we only query when the agent is actually responding

This fix maintains backward compatibility with older Proxmox versions while
supporting the new format introduced in Proxmox 8.3+.

Internal API Package

This directory contains the API server implementation for Pulse.

Important Note About frontend-modern/

The frontend-modern/ subdirectory that appears here is:

  • AUTO-GENERATED during builds
  • NOT the source code - just a build artifact
  • IN .gitignore - never committed
  • REQUIRED BY GO - The embed directive needs it here

Frontend Development Location

👉 Edit frontend files at: /opt/pulse/frontend-modern/src/

Why This Structure?

Go's //go:embed directive has limitations:

  1. Cannot use ../ paths to access parent directories
  2. Cannot follow symbolic links
  3. Must embed files within the Go module

This is a known Go limitation and our structure works around it.
