feat(analytics): Plausible snippet on every page, FAQ marked on the bootcamp

The snippet was on 10 of 40 pages, so the Trial / FAQ / Buy / Custom Quote /
search posts / Project Plan goals were inert everywhere else. It now sits
verbatim, in the same <head> position as index.html, on all 39 visitor-facing
pages. email/trial-confirmation.html is deliberately left out (email template).

FAQ: the five <details class="bc-faq"> <summary> elements on the bootcamp page
and its DE/ES twins now carry plausible-event-name=FAQ, and the 15
.faq-question buttons on de/es/support.html get the marking they were believed
to already have. No goal renamed: one FAQ goal across all languages.

No markup, copy or behaviour change, and no third-party request beyond the
snippet itself. verify-html.py PROBLEMS 0; check-links.py OK; event checker
59 PASS / 0 FAIL; impeccable detector +0/-0 findings on the changed files.
