Subject: [PATCH] test(ci): assert prerender output is only
 /hilfe/transkription

Addresses Sara's review request on #515.

Without this gate, a future regression that turns prerender.crawl
back on (or adds a new prerender entry whose nav links into
protected routes) would silently bake /, /documents, /persons etc.
to "redirect-to-login" HTML and re-introduce #514.

Verified the script catches the current broken build state:
  $ find build/prerendered ... -not -path 'hilfe/*' ...
  build/prerendered/{index,documents,persons,geschichten,stammbaum}.html
