feat(ansible): runs named by what ran where, with ago, duration and one status badge (#5125)

Runs read "update.yml on web-1" (run_title over the scope label, beside
describe_scope) on the runs list, the run page's title and breadcrumb, and
the run-started panel. The list shows started |ago (full time on hover),
|duration (counting "so far" while a run is going) and a dry-run tag.

Run statuses join STATES, so the list and the run page use status_badge:
queued dim, running info (blue, so work in progress doesn't read as a
problem), success ok "Succeeded", failed crit, interrupted warn, cancelled
dim. run_started.html leaves its hard-coded colours for tokens; the run
page's facts move to the .kv list and its failures to var(--red). Template
hex colours: 54 -> 47.

Also fixes #5124's sidebar count, which CI run 8389 failed on: the stylesheet
guard allows no weight above 500, and .nav-count asked for 600.
