feat(auth): implement secure authentication flow with RSA encryption

- Add jsencrypt and js-base64 dependencies for RSA encryption
- Create AuthGuard component for route protection
- Implement encryption utility for password security
- Refactor login page with tabbed interface and form validation
- Add login hooks for authentication state management
- Update user service to handle encrypted passwords
