bingo: serve datacenter bingo on bingo.asxp.io

Add a second public site to the same process: a 5x5 card of the 25
largest Russian datacenters where a cell is crossed out once an incident
with a public source is recorded (Yandex Sasovo and Kaluga drone strikes
on 2026-10-08/09 are seeded). config.ru dispatches by Host, so it rides
the existing container, DB and bucket instead of a new deploy.

The card is localized ru/en/uk with per-locale columns falling back to
ru. Content is managed from /admin/bingo on asxp.io, reusing AdminAuth
and CSRF. Photos go to the existing bucket under bingo/ and are proxied
by the app, so the bucket stays private and storage needs no change.

The seed data was fact-checked against operator sites and press on
2026-10-10; several entries in the original list were wrong or vague.
