Subject: Add chapter images: thumbnail on the list, headline image on the
 detail page

_chapter.html.erb (the aggregator partial used by the erfas/
chaostreffs overview pages) never rendered an image at all --
editors attaching a hackerspace photo via the asset picker would see
zero visible effect on exactly the pages they'd check first.
chapter_detail.html.erb (the individual page template) had the same
gap. Both fixed by reusing existing infrastructure rather than
inventing anything: the overview list gets a small, aspect-preserving
:thumb image beside the heading; the detail page gets the app's
existing headline_image helper, the same one every other full-page
template already uses.
