fix(android): restore user title/body after reboot so notification doesn't show fallback text

After device restart, PendingIntent extras (title, body, is_static_reminder) can be
missing when the alarm fires, so the worker took the Room/JIT path and showed
fallback text instead of the user's message.

- DailyNotificationReceiver: when intent has notification_id but missing title/body,
  load NotificationContentEntity from Room and pass title/body into Worker input
  with is_static_reminder=true.
- ReactivationManager: add getTitleBodyForSchedule(); use persisted title/body in
  rescheduleAlarm and rescheduleAlarmForBoot (and inner boot helper) instead of
  hardcoded "Daily Notification" / "Your daily update is ready".
- BootReceiver: use ReactivationManager.getTitleBodyForSchedule() when building
  UserNotificationConfig for notify schedules after boot.
- DailyNotificationWorker: when content from Room has both title and body, skip
  performJITFreshnessCheck so user text is not overwritten by fetcher placeholder.
