feat(notifications): add notification history page and API

This commit introduces the notification history feature, allowing users to view a log of their past notifications.

Key changes include:
- Added a "Notifications" link to the sidebar with a new icon.
- Defined API endpoints for fetching notification history and details.
- Added a "sent" status variant for displaying notification status.

Additionally, this commit includes related UI improvements:
- The user's full name is now dynamically displayed in the header, replacing the hardcoded placeholder.
- Table headers are now styled in uppercase for improved readability and consistency.
