Added new Blazor Server project `DbFirst.BlazorWebApp` with core UI components, pages, and static assets. Updated solution file to include the project. Also added `bootstrap.min.css.map` to support CSS debugging in browser developer tools.
- 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.
Set up multi-project solution with DbFirst API, Application, Domain, and Infrastructure layers. Implemented database-first EF Core for the Catalog entity, including domain, DTOs, repository, service, and controller. Configured AutoMapper, DI, Swagger, and project settings. Added .gitattributes and initial configuration files.
