Everruns Cloud sign-in failures return to the login page
A sign-in to Everruns Cloud that did not complete
used to leave you on the callback URL looking at a JSON error such as
{"error":"Login temporarily unavailable"}, with no way forward.
Now it returns to the login page and says whether sign-in was cancelled, the 10-minute sign-in window expired, or Everruns ID could not be reached, with a Try signing in again action. A connection failure while exchanging the login code is retried before it fails, and a malformed token response is reported as unavailable rather than as an expired link.
