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

CallForegroundService que mantiene call activa con app en background o pantalla bloqueada. Notification ongoing visible mientras dura la call. MediaSession para integrar con lockscreen controls + Bluetooth Car (mute, hangup desde audio device). Wakelock controlado para evitar drain excesivo. Notificaciones full-screen intent para incoming calls (despiertan pantalla).

Tareas

CallForegroundService (android.app.Service):
- START_FOREGROUND_SERVICE con type MEDIA_PROJECTION o PHONE_CALL (Android 14+ requiere type explicito).
- Notification.Builder channel calls con:
  - Custom view con caller name, duration, mute/hangup buttons.
  - setOngoing(true).
  - setCategory(CATEGORY_CALL).
- Lifecycle: START_STICKY para reiniciar si OS lo mata (raro con foreground).
MediaSession integration:
- MediaSessionCompat con play/pause/stop actions mapeados a mute/unmute/hangup.
- Bluetooth Car media controls.
- Lockscreen controls visibles si dispositivo lo soporta.
Wakelock:
- PowerManager.PARTIAL_WAKE_LOCK durante call activa.
- WAKE_LOCK_KEY = "matrix_client:call" para audit en dumpsys power.
- Liberar inmediato al hangup.
- Proximity wakelock (PROXIMITY_SCREEN_OFF_WAKE_LOCK) si call solo audio + telefono pegado a oreja.
Incoming call full-screen intent:
- Notification con setFullScreenIntent(pendingIntent, true).
- Activity IncomingCallActivity con showWhenLocked(true) + turnScreenOn(true).
- Compose UI fullscreen con accept/decline.
Doze mode handling:
- ACTION_IGNORE_BATTERY_OPTIMIZATIONS solicitar al user en onboarding (no obligatorio, solo para calls fiables).
- Documentar tradeoff en pantalla onboarding.
Battery monitoring:
- Log custom: call duration + battery_drain_pct al hangup.
- Visible en Settings > Diagnostics para debug.
Tests:
- Manual CallBackgroundTest — start call + Home button -> notif visible + audio sigue.
- Manual CallLockscreenTest — call + power button -> pantalla apaga + audio sigue + lockscreen controls visibles.
- Manual IncomingFullScreenTest — device en lockscreen + incoming call -> pantalla despierta + UI accept/decline.
- Manual BluetoothCarTest — Bluetooth Car connected + call active + mute desde steering wheel funciona.
- Manual BatteryTest — call 30min en background + WiFi + AC -> drain <15%.

Funciones del registry a crear

CallForegroundService_kotlin_infra — service completo.
media_session_kotlin_infra — wrapper MediaSessionCompat.
wakelock_manager_kotlin_infra — adquirir/liberar wakelocks de forma idempotente.
IncomingCallActivity_kotlin_ui — Compose fullscreen activity.
battery_monitor_kotlin_infra — log drain por session.

Acceptance

Call activa + Home -> notif ongoing visible + audio sigue 30s.
Call + power button -> lockscreen muestra controls + audio sigue.
Incoming call con pantalla apagada -> despierta + UI accept/decline.
Bluetooth Car: mute/hangup desde steering wheel funciona.
Hangup libera wakelocks (verificar con dumpsys power | grep matrix_client).
Battery saver activo: call no se corta (foreground service exempt).
Call 30min background: drain <15% con WiFi+AC.

Notas

Anti-criterios:

NO marcar done si call se corta a los 5min en background (battery optimization kill).
NO marcar done si wakelock queda colgado tras hangup (battery leak).
NO marcar done si lockscreen no muestra controls (UX critico para calls largas).

Gotchas Android 14+:

Foreground service type DEBE declararse en manifest + runtime: phoneCall|mediaProjection.
POST_NOTIFICATIONS runtime permission (Android 13+).
USE_FULL_SCREEN_INTENT runtime permission (Android 14+) — pedir explicito.

Decisiones:

Telecom framework (ConnectionService): NO en esta iteracion. Pro: integracion dialer nativo. Con: bug-prone, requiere CALL_PHONE permission con justificacion Play Store. Post-DoD considerar.
Audio focus exclusivo durante call (issue 0158 ya lo cubre).

Battery optimization onboarding:

Pantalla en primer launch: explicar por que pedimos exempt battery optimization (calls fiables).
Boton "Open settings" -> Settings.ACTION_REQUEST_IGNORE_BATTERY_OPTIMIZATIONS.
Si user declina: app funciona pero documentar que calls largas pueden cortarse.
