Add global search, in-app + push notifications, and fix card/beneficiary/scroll issues

- Global feature search for the user app, wired to the home search icon
- Notifications screen: swipe-to-delete, vanish animation, unread badge,
  and Notifee-backed foreground + background (scheduled) OS notifications
- Fix Add Beneficiary save (single source of truth via beneficiaries slice)
- Fix Cards tab scroll freeze and bottom blank space (use ScreenShell scroll)
- User-friendly toast copy across the app
- Android build tuning: parallel/caching/JVM G1 args, mobile-only ABIs
