identity.login created a live hub session every 10 min and never ended it.
It now logs out with the token it got: retried on 5xx / no response
(8 x 15 s), 401/404/410 = already over, any other 4xx fails fast, and a
cleanup it can't finish is reported as identity.logout DOWN "CLEANUP
FAILED" (alerts + red run). The hub's /auth/logout revokes every refresh
token of the account (verified live), so the next run's logout heals a
leftover; no ledger needed. Proven end to end: login 200, logout 200,
10/10 checks.
