refactor: update repository interfaces and improve dependency injection

- Refactored repository structures to use interfaces instead of concrete types, enhancing flexibility and testability.
- Updated various repository methods to accept interfaces, allowing for better dependency management.
- Modified wire generation to accommodate new repository interfaces, ensuring proper service injection throughout the application.
- Enhanced handler methods to utilize DTOs for filtering and data handling, improving code clarity and maintainability.
