Extends Docker container monitoring with comprehensive disk and storage information:
- Writable layer size and root filesystem usage displayed in new Disk column
- Block I/O statistics (read/write bytes totals) shown in container drawer
- Mount metadata including type, source, destination, mode, and driver details
- Configurable via --collect-disk flag (enabled by default, can be disabled for large fleets)
Also fixes config watcher to consistently use production auth config path instead of following PULSE_DATA_DIR when in mock mode.
Introduces granular permission scopes for API tokens (docker:report, docker:manage, host-agent:report, monitoring:read/write, settings:read/write) allowing tokens to be restricted to minimum required access. Legacy tokens default to full access until scopes are explicitly configured.
Adds standalone host agent for monitoring Linux, macOS, and Windows servers outside Proxmox/Docker estates. New Servers workspace in UI displays uptime, OS metadata, and capacity metrics from enrolled agents.
Includes comprehensive token management UI overhaul with scope presets, inline editing, and visual scope indicators.
