🚧(frontend) show recording status indicator

Room recording status triggers only when the egress worker is active.
Querying the Egress API starts the worker, which joins the room as an invisible participant.
The room is marked as "recording" only once the worker has fully joined.
Not mergeable yet.

Sadly the room event gives no information about the Egress worker’s ID.
