feat: будильник с радиостанцией + выбор битрейта по умолчанию

Будильник (Settings → Будильник): несколько будильников, время, станция, дни недели,
fade-in пробуждения. AlarmManager.setAlarmClock (вне doze) + фолбэк, BootReceiver
перепланирует после перезагрузки, AlarmReceiver→PlayerService (foreground) →
PlayerController.startAlarmPlayback (нарастание громкости). Room: AlarmEntity/Dao, БД v7.
Выбор битрейта по умолчанию в Settings (Авто/Эконом/Стандарт/Высокое) → preferredBitrate.
