fix: resolve compilation errors in ServiceCatalogs Phase 1b

- Add missing DisplayOrder parameter to ModuleServiceDto constructors
- Fix ModuleServiceListDto constructor parameter order
- Remove 'required' modifier from ValidateServicesResponse properties (conflicts with constructor)
- Update ValidateServicesEndpoint to use concrete ServiceCatalogsModuleApi type
