support huddles (#106)

* add token endpoint for livekit

* fix: invalid type passed to hook

* fix: inject livekit env variables for orion

* fix: show controls indicator above stream # shortcut

* return livekit server url from api

* simple huddle implementation with streams

* set human name in livekit room context

* simplify deployment tooling

* join huddle with audio automatically

* feat: show when there is an active huddle

This introduces a webhook which listens to events from livekit and
updates our firestore stream particle. It keeps the client simple,
reacting to changes to firestore docs.

* use headphones icon for huddles

* fix: screenshare not working in electron

The default VideoConference component from livekit doesn't support
screenshare in electron. This attempts to compose our own layout with
livekit components ourselves and introduces our own flow for
screenshare.
