Add video stall detection that monitors currentTime and auto-reconnects
after 15s of frozen video. Add MSE SourceBuffer trimming to prevent
QuotaExceededError from killing streams silently. Handle appendBuffer
errors with safe wrapper and SourceBuffer error listener. Wait for ICE
gathering before sending WebRTC offers. Add go2rtc stream availability
endpoint. Improve backend proxy error logging.

The websockets library defaults to ping_interval=20, ping_timeout=20.
go2rtc doesn't respond to these pings, so the upstream WebSocket was
being killed after ~50 seconds causing all camera streams to freeze.
Disabled ping_interval and ping_timeout on the upstream connection.
- Switch from WebRTC-first to MSE-first streaming (more reliable
across all camera types including high-res IP cameras)
- Send required {"type":"mse"} init message to go2rtc WebSocket
- Fix infinite re-render loop in configStore (pre-compute enabled
cameras instead of deriving in selector)
- Fix mqtt_bridge global variable scope in broadcast()
- Add React ErrorBoundary for visible crash reporting
- Remove unused go2rtcUrl dependency from useStream hook
