Ensure the participant requesting a mute action is still present
in the room before processing the request.
This mitigates scenarios where a previously issued token could be
reused after the meeting has ended.
Current token lifetime is intentionally long-lived and will be
refactored in the future to better align with LiveKit session
constraints. In the meantime, add this extra validation step to
reduce the attack surface.
Avoid mapping all Twirp errors to generic 500 responses.
Explicitly handle the case where a participant is no longer in
the room, as this may indicate suspicious behavior or a client
state issue.
Improve error discrimination to provide more accurate responses.
Refactor client-side LiveKit API calls to server-side endpoints
following LiveKit documentation recommendations for participant
management operations.
Replaces hacky direct client calls with proper backend-mediated
requests, improving security and following official LiveKit
