Enhance pagination and ordering capabilities in API responses

- Updated pagination-response and read-write-controllers documentation to include `orderBy` and `orderType` parameters for sorting results.
- Introduced new `order-clause` module to handle ordering logic, including validation for order types and columns.
- Enhanced `PaginationQueryDto` to support ordering fields in API requests.
- Updated various repository and service classes to implement ordering in database queries.
- Added unit tests for new ordering functionality and ensured existing tests cover the updated behavior.
- Refactored related DTOs to include user and code relations for better data representation in responses.
