The WebSocket onmessage handler captured isBroadcasting=false at creation
time. When ICE candidates arrived from remote viewers, the handler looked
up viewerPcRef instead of peerConnectionsRef, dropping all candidates.
Fix: use refs (isBroadcastingRef, viewingRef, handleWsMessageRef) so the
WS handler always reads current state. connectWs() now has [] deps and
delegates to handleWsMessageRef.current for every message.
