feat: фирменная иконка приложения + внутренний плеер записей

- адаптивная иконка лаунчера: градиентный фон (C2F25B->6FA53C) + монограмма R
  (foreground + monochrome для тем Android 13), манифест -> @mipmap
- воспроизведение своих записей ВНУТРИ приложения вместо внешнего плеера:
  RecordingPlaybackController (отдельный ExoPlayer, останавливает радио),
  RecordingPlayerSheet с перемоткой (Slider), play/pause, +/-15с, таймеры
