🐛(frontend) fix joined notification tile no longer rendering properly

The toast is enqueued on `ParticipantConnected`, which livekit-client
fires before the participant's track publications exist. At that
point `getTrackPublication(Camera)` is `undefined`, and the track
ref used by the toast is frozen that way — the toast never
re-subscribes to the participant.

Downstream effects:

* LiveKit's `useIsMuted` initializes to `false` when there is no
  publication, so the tile first paints with
  `data-lk-video-muted="false"`, which the stock CSS maps to
  placeholder `opacity: 0` — a blank box.
* Its effect then subscribes to `mutedObserver`, which defaults to
  `true` for the same situation, triggering a second render and
  only then starting the 200 ms fade-in. That render-effect-render
  transition is the visible lag behind the text.
* Because the track ref never updates, no `VideoTrack` ever mounts.
  When the camera is later subscribed, the placeholder fades out
  again, leaving the tile empty.

Re-derive the track ref inside the toast when the participant's
publications become available, so `useIsMuted` sees the real state
from the start and the tile renders the video (or a stable
placeholder) instead of a blank box.
