- Updated AuthClient to handle login and registration with new data structures.
- Enhanced AuthWrapper to manage user sessions and display appropriate messages.
- Added error handling in LoginForm and RegisterForm for better user feedback.
- Refactored user service methods to streamline user creation and verification processes.
