Say that Wise refused the signature, not that it never asked for one

A rejected signature comes back as a second 403 that carries the
rejection but no fresh token, which the old code read as an ordinary
failure and reported as a request that was never challenged.  That sent
the reader looking at the wrong request: the signature had been built and
sent, and the account's registered public key was what was wrong.
