Add CMS Management Functionality

- Introduced a new CMS management feature, including the ability to create, retrieve, update, search, and delete CMS entries. - Implemented the CMS entity, repository, service, and handler layers following Clean Architecture principles. - Added API endpoints for CMS operations in Swagger documentation, ensuring comprehensive API specifications. - Enhanced error handling and validation for CMS data, improving robustness and user experience. - Updated the main application to initialize the CMS repository and service, integrating them into the existing system.
