mas_modes.mailer.Mailer is the only outbound path (own SQLite + lock),
shared by the ticket service and both EmailMode roles. Over the cap mail
is held and reported (send-cap-reached, held); held mail is purged after
email-held-duration-max (7d) and not stored beyond emails-held-storage-max
(100MB). The ticket service's legacy outbox is imported once so the live
count carries over (checked on a copy of the live DB: 4 sent). Entrypoint
passes the cap and both limits.
