Initial .NET 8 Web API with EF Core Db-First for Catalogs

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.
