Decision (Dejan): logic condition blocks unify on a toggle — default
"Einfach" (pick a ready-made condition), toggle "Erweitert" for the pro
builder (field + operator + value). Pattern built on Wenn-Dann: the
existing dialog is the Erweitert state (toggle added, set to Erweitert),
plus a new "K-L1 Wenn-Dann einfach" frame for the simple state.
Rollout to Oder, Und, Filter still pending (each needs the missing mode
+ toggle).
