Subject: [PATCH] fix(frontend): stop screen MediaStreamTrack on PodView
 unmount

room.disconnect() removes the participant from LiveKit but doesn't stop
the underlying OS capture. Without track.stop() the screen share indicator
keeps running after Leave. beatRef already had cleanup; add the same for
screenTrackRef.
