Office: refactor livekit logic

[utkaka]

• LiveKit related code was moved to a separate class to separate it from the general office logic (still in progress though).
• There was a lot of duplicate code in Room.svelte and VideoPopup.svelte, which was moved to the new ParticipantsListView.svelte and ParticipantView.svelte components.
• Added a participant's poor connection indicator.

• Added reactions to meetings.

• Added a notification that the user is left alone in the room. If they do not react to this notification, they will be automatically disconnected

• Updated livekit-client to 2.15.5
