Deafen wrote RemoteParticipant.setVolume(0, Microphone), which EC's own
createVolumeControls overwrote with the tile volume every time sink$
re-emitted (every join / re-resolution) — so anyone joining while you were
deafened was audible — and undeafen blanket-wrote 1 to every participant,
clobbering per-tile volume/mute. The ParticipantConnected listeners also
hung off livekitRoomItems$, which is empty while alone, so the first joiner
could be heard briefly.
Deafen now drives setAudioEnabled$ -> muteAllAudio$, the `muted` prop
InCallView already passes to every audio renderer, which also silences
Track.Source.Unknown soundboard audio (the known P6-2 gap). Undeafen
restores the user's own output state and never touches the mute-all
setting. Re-applying the same state is a no-op so resendForkState() is
safe. Screenshare-audio-only mute keeps setVolume(ScreenShareAudio) but
only restores participants it muted itself. Rooms come from
allConnections$ like the sibling modules. Unit-tested.
