feat(notifications): enable foreground notifications and rollover recovery

- iOS: set UNUserNotificationCenter delegate and implement willPresent
  so notifications show in foreground and DailyNotificationDelivered is
  posted for rollover; implement didReceive for tap handling; re-set
  delegate in applicationDidBecomeActive
- Android: move DailyNotificationReceiver and BootReceiver inside
  <application>; add NotifyReceiver; extend BootReceiver with
  LOCKED_BOOT_COMPLETED, MY_PACKAGE_REPLACED, directBootAware
- main.capacitor: import daily-notification-plugin at startup so
  plugin (and recovery) load on launch
- doc: add daily-notification-alignment-outline.md

Fixes foreground notifications not showing and rollover recovery;
Android receivers were previously declared outside <application>.
