feat(register): integrate modal and toast services for success and error handling

- Add AuthService for handling login, registration, and session management.
- Create auth guards to protect routes based on authentication status.
- Implement auth interceptor to attach JWT token to HTTP requests and handle 401 errors.
- Add unit tests for AuthService, guards, and interceptor.
- Create login and registration components with form validation and error handling.
- Update routing to include guards for login and registration pages.
