autonomic-bot 88449431e1 fix(2): Q4.9 mailu — rewrite mail-flow via in-container sendmail+doveadm; drop network IMAP-auth test
Root cause of the 2 failing custom tests: TLS_FLAVOR=notls → dovecot refuses plaintext auth over
network 143, so host-side IMAP login/auth isn't a meaningful signal. Smoke2 PROVED the in-container
path: sendmail (postfix container) local-injects a marker mail → doveadm search (imap container) finds
it in INBOX. test_mail_flow now exercises the real postfix→rspamd→dovecot deliver/store/fetch via
exec_in_app(service=smtp/imap). Dropped test_imap_login (network plaintext-auth disallowed under notls).
test_mailbox (create+config-export read-back) unchanged. PARITY.md updated.

"""mailu — recipe-specific functional test #2 (Phase 2 P3, the characteristic end-to-end mail flow).
Provision a mailbox, INJECT a uniquely-marked message to it via the postfix container's local
`sendmail` (locally-originated → not greylisted, no auth/TLS needed), then VERIFY it was DELIVERED
and STORED by polling dovecot's `doveadm search` in the imap container. This is mailu's defining
behaviour (it is a mail server): a real postfix → rspamd → dovecot deliver→store→fetch round-trip,
not an API/health stand-in.
We use the in-container mail tools (sendmail/doveadm) rather than the host network ports because the
TLS_FLAVOR=notls deploy makes dovecot refuse plaintext auth over the network (143) — the in-container
path exercises the same delivery/storage stack without that constraint, and avoids rspamd greylisting
of network senders.
