bingo: move the public site to the datacenterbingo repo

The public card now runs from its own repo and container, with a
Traefik router of its own. Drop BingoWeb, its views, icons, Host
dispatch and the asxpio-bingo router here; keep the admin, the schema
and the photo pipeline, which the new site reads through a read-only
role.

BINGO_HOST stays for IndexNow pings and the admin's site link.
