Delete Connection

Remove a workspace connection and anything parked for it. Idempotent.

Both outcomes are a 200: the contract wants resource_status, and a retry of an already-applied delete is a success, not a 404.

A workspace with no rows may still be holding the payload connect parked, which is what it answered configured_resources about. Leaving that behind would let an admin redeem a connection Databricks believes is gone, so a discarded payload is itself a delete.
