Ring shift alerts like a soft alarm instead of a single ping

[SishirP17]

What

The 30-second pre-shift notification now rings like a soft alarm instead of playing the phone's default one-shot notification ping.

• Bundles a synthesized 28 second ding-dong chime (assets/sounds/shift_alarm.wav) through the expo-notifications config plugin. iOS caps notification sounds at 30 seconds, so the chime rings for roughly the whole lead-in window.
• Android: the sound plays on the ALARM audio stream, so it rings at the user's alarm volume (like their morning alarm) even when notification volume is turned down. Silent mode and DND still follow OS rules.
• Android channels are immutable once created, so the sound change ships as a new shift-alerts-v2 channel. The old shift-alerts channel is deleted on the next ensureShiftAlertChannel() run so users don't see a stale duplicate in the app's notification settings.
• iOS reads the sound from the notification content; same shift_alarm.wav is used there.

Notes

• The custom sound needs a real build (the config plugin bundles the asset at prebuild). Expo Go falls back to the default notification sound; everything else keeps working.
• Existing behavior is unchanged otherwise: tap still deep-links to the clock-in screen, foreground haptic tick still fires, alerts still cancel on logout.

Verification

• npm run typecheck: clean
• npm test: 15 files, 106 tests passed
• npm run lint: clean
• Sound asset audited: 16-bit PCM mono WAV, 28.0s, soft peak normalized
