How to complete the challenge `POST /challenger (existing X-CHALLENGER)`

This persistence challenge restores a saved challenger by sending a POST request to /challenger with the existing challenger GUID in the X-CHALLENGER header.

It differs from creating a new challenger because the request includes an existing X-CHALLENGER value and expects the server to restore that challenger rather than create a new one.
