Dashboard: hide archived sessions from the All-sites list (hc-7vo)

Follow-up to the archive feature: archived healthchecks showed in both the
main All-sites list and the Archived section. allSitesSummary() now excludes
archived sessions from the aggregate (and from the per-site "latest session"
detail), so a site whose sessions are all archived drops off the main list
and appears only under "Archived". A site with a mix keeps its row, counting
only its live sessions. The per-site page still lists every session.

Also bumps the server version baseline in config.php.example to 0.1.8.

2 new tests (51 total).
