- Root cause of the 502s: ImapFlow had no connect timeout, so a wrong host/port
(e.g. IMAP on an SMTP port) hung the request until the proxy returned 502 with
no message. Added connectionTimeout/greetingTimeout/socketTimeout + a hard
connectWithTimeout() race on every IMAP client (detect/test/roundtrip/poll).
- Error routes now return 422 with the underlying reason (was 502, which
collided with the proxy's own 502 and hid the message).
- New 'Check now' button + POST /incoming-config/poll runs the poller on demand
(respects the incomingMail flag) and reports disabled/unconfigured/busy or N
ingested — so 'nothing in Received' is diagnosable without waiting 60s.
