Subject: [PATCH] =?UTF-8?q?=E2=9C=A8(backend)=20expose=20is=5Fauthenticate?=
 =?UTF-8?q?d=20in=20the=20LiveKit=20token?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Include the is_authenticated flag on the user in the LiveKit token
and participant metadata.

The frontend needs this information (used in the next commit) to
know whether it can offer to promote a user with access to the room
admin.
