Add static color support, HAOS light entity, and real-time profile updates

- Add static_color capability to WLED and serial providers with native
  set_color() dispatch (WLED uses JSON API, serial uses idle client)
- Encapsulate device-specific logic in providers instead of device_type
  checks in ProcessorManager and API routes
- Add HAOS light entity for devices with brightness_control + static_color
  (Adalight/AmbiLED get light entity, WLED keeps number entity)
- Fix serial device brightness and turn-off: pass software_brightness
  through provider chain, clear device on color=null, re-send static
  color after brightness change
- Add global events WebSocket (events-ws.js) replacing per-tab WS,
  enabling real-time profile state updates on both dashboard and profiles tabs
- Fix profile activation: mark active when all targets already running,
  add asyncio.Lock to prevent concurrent evaluation races, skip process
  enumeration when no profile has conditions, trigger immediate evaluation
  on enable/create/update for instant target startup
- Add reliable server restart script (restart.ps1)
