Bug Report
Two people can join one room under the same display name. The tiles, the participant list and the waiting room all show the same string.

Where it costs something:
- a moderator admits one of two identical rows in the waiting room, with nothing to tell them apart
- muting or removing someone means choosing between two identical rows
- the recording metadata and the transcript name both speakers the same
- anyone can type the name of someone already in the room
Nothing checks the name at join.
