feat: add PostgreSQL support and enhance evaluation loading

- Added `pg` and `@types/pg` dependencies for PostgreSQL integration.
- Updated `useEvaluation` hook to load user evaluations from the API, improving data management.
- Refactored `saveUserEvaluation` and `loadUserEvaluation` functions to interact with the API instead of localStorage.
- Introduced error handling for profile loading and evaluation saving to enhance robustness.
- Added new methods for managing user profiles and evaluations, including `clearUserProfile` and `loadEvaluationForProfile`.
