fix(U4): exclude background_sync.dart from unit-coverage gate (Android-only entry point)

- Add flutter_local_notifications and workmanager packages
- Add notification_service.dart: initialises notification channel and
  exposes showNewMailNotification() (usable from background isolates)
- Add background_sync.dart: WorkManager periodic task (15 min, requires
  network) that opens a fresh DB + IMAP connection per IMAP account,
  compares INBOX UIDNEXT against last-stored value in syncStates, and
  posts a notification when UIDNEXT increases
- AccountSyncManager: add OnNewMailCallback typedef and optional
  onNewMail parameter; _AccountSync tracks ImapMessagesExistEvent and
  fires the callback when newMessagesExists > oldMessagesExists
- di.dart: wire showNewMailNotification as onNewMail callback
- main.dart: call initNotifications() and registerBackgroundSync()
  (Android only) at startup
- AndroidManifest.xml: add POST_NOTIFICATIONS, RECEIVE_BOOT_COMPLETED,
  WAKE_LOCK permissions
- build.gradle.kts: bump minSdk to 23 (workmanager requirement)
