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.
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.
Implemented FavoritesModule to manage user favorites. Includes service methods for adding, removing, and listing favorites, along with appropriate database integrations and API endpoints.
