Issue #2914933: Add service tags to order-related interfaces
requested to merge issue/commerce-2914933:2914933-document-service-tags-service-interfaces into 3.0.x
Added doc comments to specify the service tags for OrderTypeResolverInterface, OrderPreprocessorInterface, AvailabilityCheckerInterface, and OrderProcessorInterface. This change ensures that each interface explicitly declares the services it should be tagged with, improving clarity and maintainability.
Closes #2914933
