refactor(core): remove unused fields from ContentService

Remove fields that are now handled by extracted services:
- IDocumentBlueprintRepository (BlueprintManager)
- IPropertyValidationService (extracted services)
- ICultureImpactFactory (extracted services)
- PropertyEditorCollection (extracted services)
- ContentSettings + optionsMonitor.OnChange callback
- IRelationService (ContentMoveOperationService)
- IEntityRepository (unused)
- ILanguageRepository (extracted services)

Keep _shortStringHelper temporarily (will move to ContentCrudService in Task 5).

Simplify constructor to only inject dependencies still used directly.
Update UmbracoBuilder.cs DI registration to match new constructor.
