feat(auth): add debug logging for authentication processes

- Introduced detailed console logging in the auth controller, deserialize, serialize, and passport strategies to aid in debugging authentication flows.
- Enhanced error handling and response messaging during user registration and login processes, providing clearer feedback for success and failure scenarios.
- Updated the signup and login functions to include more informative logs, improving traceability of user actions and system responses.
