Backend changes (session-coordinator):
- Add PublishParticipantJoined method to JoinSessionMessageRouterClient interface
- Implement PublishParticipantJoined in MessageRouterClient to broadcast events
- Call PublishParticipantJoined in join_session.go after participant joins
- Add detailed logging for debugging event broadcast
Android changes (service-party-android):
- Add detailed logging in TssRepository for session event handling
- Add detailed logging in MainViewModel for participant_joined processing
- Log activeSession state, event matching, and participant updates
This enables the initiator's waiting screen to receive real-time updates
when participants join the session, matching the expected behavior.
