Screen.Recording.2025-01-17.at.1.07.37.PM.mov

What changed?

• Created useRespondToNotification mutation hook to handle notification responses
• Added empty state message when no notifications exist
• Implemented notification confirmation and deletion in the NotificationCard component
• Added mock data for habit completions to support testing

How to test?

1. Navigate to the Notifications tab
2. Try accepting a friend request - verify the friendship is established
3. Try accepting a habit invite - verify you're added as a participant
4. Try rejecting any notification - verify it's removed from the list
5. Clear all notifications - verify the empty state message appears
