Updated project and solution files to rename and restructure `DocumentOperator` to `DocumentService`. Modified project references in `DocumentService.API.csproj`, `DocumentService.Application.csproj`, and `DocumentService.Infrastructure.csproj` to reflect the new naming convention. Updated `DocumentService.sln` to remove old project references, add new ones, and adjust configuration and nested project mappings accordingly. This change aligns the project structure with the new naming convention.
