- Split `CatalogDto` into `CatalogReadDto` and `CatalogWriteDto` for clear separation of read/write operations in both backend and frontend. - Updated API controllers, services, and AutoMapper profiles to use new DTOs; ensured audit fields are set in service layer. - Enabled CORS in the API project to support Blazor WASM frontend. - Added new Blazor WebAssembly project (`DbFirst.BlazorWasm`) with catalog management UI, API client, Bootstrap v5.1.0 styling, and configuration-driven API base URL. - Included `bootstrap.min.css` and its source map for frontend styling and easier debugging. - Updated solution file to include new project and support multiple build configurations. - Result: improved API design, clean DTO separation, and a modern interactive frontend for catalog management.
