Fix/transition sound not playing (#58)

* Set AudioAttributes on ringtone before play

Assign AudioAttributes to the Ringtone with USAGE_ALARM and CONTENT_TYPE_SONIFICATION before calling play(). This ensures correct routing/behavior (volume, focus, and stream selection) on modern Android versions and avoids unexpected muted/incorrect stream playback. Kept nullable-safe access to ringtone.

* Update FocusModeService.kt
