fix(notifications): Return Notification object from create_notification_async

- Changed return type from bool to Optional[Notification]
- In EAGER mode (tests), query and return created Notification
- In fallback mode, return created Notification object
- Fixes integration tests where code expected Notification object

Previously returned True/False which broke code expecting notification.id
attribute. Now properly returns the created Notification instance or None.
