EML_BOUNCE
E-mail bounce / delivery failure detected
A delivery failure was recorded — either an inbound bounce message (DSN) parsed from the mailbox, or an outbound send rejected by the upstream server. Structured detail (which contact, which enhanced status code, verbatim SMTP response) lives in `brj__emailer_delivery_event`; this log entry is the operator-visible summary. Debounced per-organisation so a burst of bounces does not spam the log.
