A 401 whose error body failed mid-read (e.g. unexpected EOF) was wrapped
as retryable by the body-read path, letting the outer reconnect loop
re-enter fetchTicket and refresh again on every iteration, bypassing the
single refresh-retry guard.
Classify non-2xx responses by status first; the body is only drained
best-effort since it is never used for error reporting here. 401 stays
fatal regardless of body state, while 2xx body-read failures remain
retryable transport errors.
