bingo: move to datacenterbingo.xyz

The card gets its own domain instead of a subdomain of the IE site.
www. is routed to the same container and 301-redirected to the apex in
config.ru, so there is one canonical host for links and the cert.

 - 5×5 card of the 25 largest Russian datacenters; a cell is crossed out when an incident (with a public source) is recorded. Rows/columns/diagonals → BINGO banner.
 - Locales `ru` / `en` / `uk` at `/ru`, `/en`, `/uk`; `/` redirects by `Accept-Language` (fallback `en`). Per-locale DB columns (`name_*`, `city_*`, `title_*`); `ru` is required, others fall back to it. UI strings in `Bingo::T` (`lib/bingo.rb`).
