merge: fj/feat/android-voip-client — congestion fix, AEC toggle, debug logging

Merged 10 commits from Android branch:
- Send task crash fix on QUIC congestion (continue instead of break)
- AEC toggle + NoiseSuppressor on Android
- Debug reporter for crash diagnostics
- Mic mute crackling fix
- Participant dedup in UI
- Proper QUIC connection close on hangup
- Null alias display fix
- Tracing → Android logcat
- Incident reports for send-task crash and playout ring desync

Conflict resolved in room.rs: kept Android's improved debug logging
(recv gap tracking, lock contention, forward latency, send errors)
inside our media_task async block for parallel signal handling.
