Real club crests, and no more crash on "Verein hinzufügen"

Crests are resolved from the German Wikipedia page summary at runtime and
cached per device, so nothing copyrighted is stored in the repository. The
coloured shield remains as the fallback while the badge loads or when a
club has none.

The add dialog crashed for the same reason the rail did: it focused a row
that only exists when something is preselected, and adding a club has no
preselection. It now also scrolls, which 56 clubs rather need.

CI: this Gitea resolves bare action names against itself, so the workflow
now uses full GitHub URLs, and it runs the unit tests too.
