Live portal: React + dockview multi-stream viewer behind Authentik; MediaMTX HLS/WebRTC/API re-enabled; is-live Discord hook

live/: every active stream opens as a dockable window (WHEP, HLS fallback), audio follows the
focused window, per-window mute/volume, pinning. Caddy live.HOST block with forward-auth proxies
/api /webrtc /hls to MediaMTX on loopback and serves /srv/live. WebRTC media on 8189 (firewall).
configure.py asks the live hostname and an optional Discord webhook; MediaMTX -ffmpeg image runs
the runOnReady hook. deployLive.sh builds and ships dist/.
