Added CatalogUpdateProcedure enum to domain. CatalogWriteDto now includes UpdateProcedure property in both application and BlazorWasm layers. Catalogs.razor form allows users to choose between PRTBMY_CATALOG_UPDATE and PRTBMY_CATALOG_SAVE when editing. Repository, service, and handler layers updated to pass and use the selected procedure. Default remains Update. Updated comments and TODOs for clarity and future refactoring.
- 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.
