Add Notification History Tab for Admin Notifications

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

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

No files, tests, or entry points are named. Begin by locating the backend notification and admin-interface entry points, then determine how notifications are currently created and stored. Done should include an accessible history with the requested review, filtering, retention, deletion or archiving, and triggering behavior.
