asxpio now probes public hosts tied to each datacenter once a minute
and stores 5-minute rows (bingo_monitor_* tables, granted to the
read-only bingo role). Show them: /:locale/status lists every monitored
site with its current state and a 24-hour bar, /status.json has the
same data, and monitored datacenter pages get a small block.

A site is down only when nothing answered for two buckets. Everything
reads as unknown when the worker is stale or fewer than half of the
control hosts in Russia answer, since probes run from Finland and
filtering can look like an outage. The page says plainly that this is
not an incident record.

Refresh test/schema.sql for asxpio's migration 017.
