analytics: record and show the rendered content language of page views

GETs store the resolved page language, activity pings carry <html lang>
(including a new ping on in-place language switches, which also keeps the
switch's GET out of crawler classification), and trail items/crawler hits
surface it. The viewer shows flags discreetly: nothing on single-language
sites or primary-language-only rows, one leading flag for uniform visits,
transition flags on mixed trails, a flag row per crawler.

first-seen targets in order; `read` updates accumulate active seconds on

the trail item matching `fr` (preferring the item whose language matches
the report, so seconds after a language switch land on the new-language

the client's latest GET for that path — preloads included, which is what
allows 404 pages to render red in the viewer even when the navigation

rendered language: the client's report, for the entry page falling back
to its GET's rendered language (old clients don't send one); a page
re-visited in a different language becomes a distinct trail step instead
of merging into the existing item. The entry page's referer and
