Sign out everywhere else: every other WorkOS session of the person, and their other devices' credentials

The person's session. Ends every WorkOS session of the person but the caller's own (WorkOS lists them, so a session no device row records, one made before devices recorded sessions, is ended too), records each as ended, so its access tokens are refused on their next request, and clears the credential of every other device of the person. The caller's device is the one its session is recorded against, else the one X-Six-Minute-Device names. Answers how many sessions and device credentials it ended.
