fix(rc+guest): coordinate/keyboard/UI for remote control; guest media + panel fixes (batch71)

Browse Source 
Remote control (connect.html viewer):
- Coordinate offset fixed: map clicks to the actual video CONTENT rect (object-fit
  letterbox-aware), not the element rect — cursor now lands where you click.
- Keyboard: capture at document level while a session is live (the <video> lost
  focus on bar clicks → keys did nothing). Skips the chat input.
- Control bar moved to bottom-right with tiny modern icons; video fills the viewport.
- Smoother cursor (mousemove ~60/s).

Guest meetings:
- Guest mic inaudible + guest invisible in the participant list + outsider screen
  share not showing (#1/#8/#11): root cause was the SFU media→tile map keyed on
  identity==uid, but guests had a random LiveKit identity and a null signaling uid.
  Guests now carry ONE stable id across signaling (meeting-join guestId) and the
  LiveKit token identity, so their media attaches and they appear to everyone.
- Guests can't add participants (#9) and don't see the transcript button (#12).
- Search box in the schedule participant list (#10).
