Initial commit: Camera Viewer with Frigate alerts
Features: - 8-camera WebRTC grid using go2rtc - MQTT subscription to Frigate events - Auto-fullscreen on person detection (Front_Porch) - SSE for real-time browser updates - Touch-friendly tablet interface - Wake lock to keep screen on - Auto-dismiss after 30 seconds
