egutierrez daef7ea190 feat(matrix): MAS migration helpers + 2 flows + 15 issues + capability group
Helper functions (matrix-mas capability group):
- mas_client_register_bash_infra: register/sync OAuth clients via mas-cli
- mas_syn2mas_migration_bash_infra: dry-run + apply user migration to MAS
- synapse_msc3861_enable_go_infra: edit homeserver.yaml MSC3861 block (with diff)
- wellknown_oidc_patch_go_infra: patch well-known JSON with msc2965.authentication
- synapse_login_flows_check_go_infra: health-check post-migration login flows

Flows + issues for custom Matrix clients (PC + Android):
- 0010 matrix-client-pc: Wails + React+Mantine (issues 0147-0153)
- 0011 matrix-client-android: Kotlin + Compose (issues 0154-0161)
- 0162 enable MAS as auth provider (Synapse delegate) — EXECUTED on VPS
- 0163 custom admin panel propio (sustituye synapse-admin)

Production state (organic-machine.com):
- Synapse migrated SQLite -> Postgres
- MSC3861 active, password_config disabled
- 21 users + 41 access_tokens migrated via syn2mas
- 4 MAS clients registered (element, matrix_pc, matrix_android, admin_panel)
- synapse-admin container removed + Coolify route deleted
- well-known patched with org.matrix.msc2965.authentication

## Objetivo
Llamadas nativas via `io.livekit:livekit-android` SDK oficial. Codecs HW (H.264/VP9 hardware decoder), audio focus + AEC/NS nativos, MediaSession para controls en lockscreen, Picture-in-Picture mode Android nativo. Soporta 1:1 + grupales (limite 16 del LiveKit config actual).
## Tareas
1. Backend (compartido con cliente PC):
- Reusar `livekit_token_gen_go_infra` que esta en flow 0010.
- Cliente Android pide token al mismo endpoint `/api/call/token` que el cliente PC.
2. ViewModel:
- `CallViewModel(matrixClient, roomId)`:
- `joinCall()` — pide token + conecta `Room.connect()`.
- `toggleMic()`, `toggleCamera()`, `toggleScreenShare()`.
- `hangup()`.
- `Flow<CallState>` con participants, tracks, connection state.
3. Compose:
- `CallScreen` fullscreen:
- Grid tiles participantes (`Flow` layout responsive 1/2/4/9/16).
- Tile principal: active speaker (track audio level del SDK).
- Controles bottom: mic, cam, screen, raise hand, hangup.
- `IncomingCallScreen` fullscreen con accept/decline (system overlay activity).
- `CallTile` composable con `VideoView` (SurfaceViewRenderer del SDK).
4. PiP (Picture-in-Picture):
- `Activity` con `setPictureInPictureParams()`.
- Auto-enter PiP al minimizar la app durante call.
- PiP tile: video remoto + boton hangup.
5. Audio routing:
- `AudioFocusRequest` (Android 8+) — focus exclusivo durante call.
- Switch speaker/earpiece/bluetooth via `AudioManager.setSpeakerphoneOn()` + connection state listeners para audifonos BT.
- Echo cancellation + noise suppression: SDK los habilita por defecto, verificar.
6. ICE/TURN: igual que cliente PC, depende del LiveKit config server-side.
7. Tests:
- Instrumented `Call1to1Test` con emulator + segundo cliente (PC) — connect, video, hangup.
- Manual `ScreenShareTest` con device fisico.
- Manual `4ParticipantsTest`.
- Manual `PiPTest` — call activa + Home button -> PiP aparece.
## Funciones del registry a crear
- `livekit_call_kotlin_infra` — wrapper `Room` SDK + permission helpers.
- `audio_routing_kotlin_infra` — speaker/earpiece/BT switching.
- `CallScreen_kotlin_ui` — fullscreen call UI.
- `CallTile_kotlin_ui` — tile con VideoView.
- `IncomingCallScreen_kotlin_ui` — accept/decline overlay activity.
## Acceptance
- [ ] Start call desde Android -> PC Wails recibe y conecta.
- [ ] 30s call con video+audio nativo (verificar HW codec via `adb shell dumpsys media.codec`).
- [ ] Mute mic + apagar cam refleja en otro cliente.
- [ ] Screen share desde Android (con `MediaProjection`) visible en PC.
- [ ] PiP: minimizar app durante call -> tile flotante con video remoto.
- [ ] Bluetooth headphones: cambio automatico al conectar/desconectar.
- [ ] Battery: call 30min con AC + WiFi <15% drain.
## Notas
- Permissions runtime: `RECORD_AUDIO`, `CAMERA`, `POST_NOTIFICATIONS` (Android 13+), `FOREGROUND_SERVICE`, `FOREGROUND_SERVICE_MEDIA_PROJECTION` (Android 14+).
- Foreground service requerido para mantener call con app en background (issue 0161).
- E2EE en call (insertable streams): TBD post-DoD, igual que en cliente PC.
- Connection service Android (sistema): TBD, opcional. Permite integracion con dialer system + Bluetooth Car. Valorar coste/beneficio.
