Implement account deletion handling and improve user feedback

- Added checks for accounts marked for deletion in signup, verification, and password reset processes.
- Updated reward and task listing to sort user-created items first.
- Enhanced user API to clear verification and reset tokens when marking accounts for deletion.
- Introduced tests for marked accounts to ensure proper handling in various scenarios.
- Updated profile and reward edit components to reflect changes in validation and data handling.
