Returns a list of orphan Datamart objects. Identifies and returns details about objects considered obsolete. Objects such as:

• Datamart Tables with missing owners.
• Data Loads for which the target Field Cache was deleted.
• Analytics (PriceAnalyzer) tables without a matching deployed Field Cache (FC).

By default this endpoint works in the dry run mode to mitigate accidental deletions. Actual deletions require adding explicit /delete in the endpoint URL.
