Refactor multiple modules to improve dependency management by adding missing imports (e.g., `AuthModule`, `CryptoModule`) and ensuring essential services and repositories are exported. Update Dockerfile for better build and runtime efficiency, improve CORS handling, and enhance validation with updates to DTOs. Include package.json refinements for dependency organization.
Deleted unused e2e tests, mocks (`cuid2`, `jose`, `ml-kem`, `sha3`), and their associated jest configurations. Simplified services by ensuring proper dependency imports, resolving circular references, and improving TypeScript type usage for enhanced maintainability and testability. Upgraded Dockerfile base image to match new development standards.
Introduce repository pattern across multiple services, including `favorites`, `tags`, `sessions`, `reports`, `auth`, and more. Decouple crypto functionalities into modular services like `HashingService`, `JwtService`, and `EncryptionService`. Improve testability and maintainability by simplifying dependencies and consolidating utility logic.
Integrate `Logger` for consistent logging in services like `reports`, `categories`, `users`, `contents`, and more. Introduce caching capabilities with `CacheInterceptor` and manual cache clearing logic for categories, users, and contents. Add request throttling to critical auth endpoints for enhanced rate limiting.
Added unit tests for the `api-keys`, `auth`, `categories`, `contents`, `favorites`, `media`, and `purge` services to improve test coverage and ensure core functionality integrity.
Implemented FavoritesModule to manage user favorites. Includes service methods for adding, removing, and listing favorites, along with appropriate database integrations and API endpoints.
