design: the DMARC hub names the form of a hosted address, not a server mailbox

The owner's decision (2026-10-10): the mailbox for the server as a
whole, dmarc-reports@<hostname>, goes. Under the three-choice scheme a
domain can only choose its own hosted address, so nothing can be told
to report to the general one. The Ingest box's fact becomes "Hosted
addresses: dmarc-reports+<domain>@<hostname>".

check.py: 0 violations; outlines.json unchanged.
