1.0.12: список записей по долгому тапу на кнопку записи

- Long-press (3 с) кнопки записи открывает диалог со списком
  файлов recordings/*.ogg.
- В диалоге: воспроизведение (MediaPlayer, переключатель
  play/stop) и удаление с подтверждением.
- Пустой список — тост «Нет записей».
- Иконки ic_play/ic_stop/ic_delete, разметка dialog_recording_item.
