Listens for ParticipantDisconnectedEvent on the LiveKit Room. When no
remote participants remain (1:1 call ended by other side), waits 5
seconds then auto-hangs up. The delay allows for brief reconnections.
Also ensures our app properly cleans up when Element X user hangs up
on their end — our side won't sit connected to an empty LiveKit room.

_RemoteVideoView and _LocalVideoPip watched the Riverpod provider but
not the LiveKit Room's ChangeNotifier. When a remote participant joined
or published a track, notifyListeners() fired but no widget rebuilt.
Fix: wrap both views in ListenableBuilder(listenable: room) so they
rebuild on every Room event (participant connect, track subscribe, etc).
Added _AudioOnlyPlaceholder for when remote has audio but no video.

Calls:
- JWT fetch now uses correct MSC4143 flow: get OpenID token from
Synapse, then POST to /_matrix/livekit/jwt/sfu/get (was using
GET with Bearer token to wrong path — returned 301→404)
- Error messages now visible for 3 seconds before popping screen
(was flashing away instantly — user couldn't see failure reason)
- Voice vs video calls differentiated via ?video=0/1 query param
- Debug logging added to JWT flow for troubleshooting
Messages:
- Chat timeline now shows newest at bottom (standard behaviour).
Was reversed twice: SDK returns newest-first, code reversed to
oldest-first, then ListView(reverse:true) put oldest at bottom.
Removed the extra .reversed — newest-first + reverse:true = correct.
