ScreenTinker 0cd2a904e5 Android player: video-wall (wall:sync) support
Ports the wall:sync protocol the web and Tizen players already ship to native
Kotlin/ExoPlayer, so the Android player can join a video wall.

- WallController (new): 4Hz leader broadcast; follower latency-compensated drift
  controller (hard-seek past 0.3s, gentle +/-3% playbackRate nudge past 0.05s);
  role handling with immediate align on entry and on wall:sync-request. Per-tile
  rotation intentionally not applied (web/Tizen parity; left as a TODO).
- MediaPlayerManager: expose position/duration/seekExact/setSpeed for the drift
  controller; RESIZE_MODE_FILL / ImageView FIT_XY in wall mode (object-fit:fill
  parity), restored to fit/fitCenter on exit. Follower mute (setWallMute) persists
  across leader-driven item switches, and followers loop (REPEAT_MODE_ONE) so they
  never freeze on the last frame if the leader's next index is late.
- PlaylistController: wallFollower flag suppresses auto-advance (leader drives the
  index); getIndex/gotoIndex for follower tracking; itemStartedAtMs for non-video
  sync position.
- WebSocketService: onWallSync/onWallSyncRequest handlers (posted to the main
  thread since they drive ExoPlayer) + emitWallSync/emitWallSyncRequest senders
  guarded on socket.connected() like sendPlaybackState.
- MainActivity: parse wall_config in onPlaylistUpdate and branch before the
  orientation + multi-zone paths; size/translate rootView to this screen's slice;
  exit() restores full screen.

Compiles clean (./gradlew :app:assembleDebug). NOT yet validated on a device or a
real wall — the ExoPlayer seek/speed sync and the slice transform need on-device
tuning before this is trusted.
