9 tasks adding voice calls (1:1 + group) to the mobile app over the
same LiveKit + Supabase signaling stack the desktop uses:
1. @livekit/react-native + @livekit/react-native-webrtc deps, mic
permission strings, audio background mode, LiveKit Expo plugin.
2. callSignal.ts subscribe/publish helpers over Supabase realtime.
3. callContext.tsx state machine (idle/outgoing/incoming/connecting/
connected/ended) + LiveKit room lifecycle + audio routing.
4. IncomingCallModal at root with Annehmen/Ablehnen.
5. Mount CallProvider + global IncomingCallModal in _layout.tsx.
6. Register /call full-screen modal route.
7. In-call screen with participants list + mute/speaker/hangup.
8. Phone-icon header button on conversation detail + push to /call
on connect.
9. Workspace typecheck pass.
Out of scope: video, CallKit / ConnectionService native UI, VoIP push
wake-up, screen sharing, call history. Those are Phase 3.5 / 4.
