Follow work that answered 202

The read-back for every route here that answers 202 (app-insight, autofix). Poll it every couple of seconds until status is done — result is then the body the route would have answered with — or failed, where error carries the status and message it would have refused with. A running operation older than the platform restart window reads as failed with a message saying so. Rows are kept seven days. Readable by a session, or by a key holding the scope the starting route required; any other company's id is a 404.
