Cédric Verstraeten 730b1b2a40 Add WebRTC liveview signaling and UI fallback ...

Introduce structured WebRTC handshake signaling and client-side fallbacks. Changes:

- machinery: replace HandleLiveHDHandshake channel to carry LiveHDHandshake (payload + signaling callbacks) and expose active WebRTC reader count in dashboard data.
- routers: MQTT and WebSocket handlers now send/receive LiveHDHandshake structs; websocket supports stream-hd and webrtc-candidate messages and uses callback-based signaling to reply over the WS connection.
- webrtc: add helper functions to send MQTT or callback answers/candidates, adapt InitializeWebRTCConnection to the new handshake type, and expose GetActivePeerConnectionCount.
- utils: minor GetMediaFormatted filtering fix and unit test for timestamp range behavior.
- ui: Dashboard gains native WebRTC liveview with fallback to SD image stream, shows active listener count, and handles signaling/candidates; Media page adds datetime range filters, infinite-scroll append behavior, and styles; reducer/action updates to support appending events; package.json scripts disable ESLint plugin during start/build/test.

These changes enable browser-based HD liveviews with dual signaling paths (websocket callbacks or MQTT), improve media filtering, and provide graceful fallback to SD streaming when WebRTC fails.
