Add Notification History Tab for Admin Notifications

Nobody has claimed this yet.

**Is your feature request related to a problem? Please describe.**
The Enatega Admin website should include a Notification History Tab, where all notifications are saved and can be accessed by the admin at any time. This would help admins refer back to previous system messages, alerts, and important updates whenever necessary.

**Describe the solution you'd like**

1. Add a Notification History section within the admin interface.
2. All notifications (system alerts, updates, warnings, etc.) should be saved in the history tab.
3. Admins should be able to access past notifications, review them, and possibly even filter by date or type of notification.
4. The notifications should remain in the history until an admin decides to delete them or archive them for future reference.
5. Admins should be able to trigger and view notifications from this history tab at any time.

No files, tests, or entry points are named. First map the admin interface and existing notification flow, including where notifications are created and stored. Done should include a history tab where admins can review, filter, retain, delete or archive, and trigger notifications.
