Rank by operational sites; show what each status check probes

The datacenter text said "No. 33 by power" for a site that is 25th
on the default card, because it counted construction projects. Rank
among operational datacenters only, matching the card, and leave the
rank out for sites not yet in service. data.json and status.json gain
an operational_rank next to the list position.

The status page now lists, under each site, the hosts it probes with
their label, last result and the source that ties them to the site,
folded away behind a click; the control hosts in Russia get the same
list, and datacenter pages show it under their reachability block.
status.json carries the same targets.

For search: a keyword title tagline and meta description, WebPage and
Dataset structured data (pointing at status.json), x-default, and the
status pages in the sitemap.
