The contributor generator (person.py in q02/pool-publication-page) already
writes `active: false` into a person's front matter once the defined end
date of their project association in the knowledge pool has passed. The
redesigned contributors page had stopped evaluating that flag, so former
members were listed among the current ones.
Contributors are now split into a current grid and a "Retired" section
below it, plus a "Retired" filter button that is only rendered when
somebody actually is retired. Both grids hide themselves when a filter
leaves them empty. Card markup moved into a partial so the two grids
cannot drift apart.
Contributors carrying no `active` flag at all (those without any project
association) count as current — a missing flag means "never evaluated",
not "ended".
Also fixes the German page, which rendered bare taxonomy terms (slug
names, no portraits, no metadata) because the person records only exist as
English content files: it now uses the same layout and page set. And the
section illustration is resolved through the page bundle, since a bare
"people.png" resolves to /de/contributors/people.png and 404s.
