wip

AUTHENTICATED_PARTICIPANTS_CAN_EDIT_DISPLAY_NAME was only enforced at
LiveKit token generation and by hiding the name field in the frontend.
The `rooms/{id}/rename/` endpoint never checked it, so any authenticated
user with a valid room token could rename themselves via the API even
when the self-hoster had disabled it.

Return 403 from the rename action for authenticated users when the
setting is disabled, mirroring the `can_edit` rule in
`core.utils.generate_token`. Anonymous participants are unaffected, as
they have no account name to fall back on.

Add tests covering the disabled/enabled cases for authenticated users
and the anonymous exception.
