feat(core): register IContentQueryOperationService in DI container

Adds unique registration for ContentQueryOperationService matching
the Phase 1 pattern for IContentCrudService. Also updates the
ContentService factory to inject the new service as the 19th parameter.

Note: Build will fail until Task 4 adds the 19-parameter constructor
to ContentService.
