feat: enhance evaluation loading with cookie authentication

- Updated the GET method in the evaluations route to support user authentication via cookies, improving security and user experience.
- Added compatibility for legacy parameter-based authentication to ensure backward compatibility.
- Refactored the useEvaluation hook to load user profiles from cookies instead of localStorage, streamlining the authentication process.
- Introduced a new method in EvaluationService to retrieve user profiles by ID, enhancing data retrieval efficiency.
- Updated ApiClient to handle cookie-based requests for loading evaluations, ensuring proper session management.
