First automated tests in the backend. Fakes Prisma + SyncService in
memory and asserts on the zuteilung.createMany payload:
- Force-Zuteilung wins over participant wishes
- wish-round fallback when a workshop hits capacity
- participant left unassigned when nothing is free
- underfilled-workshop consolidation reassigns via remaining wishes
- workshop exactly meeting minTeilnehmer is kept
- one CREATE sync entry captured per resulting Zuteilung
npm test green (9 tests). Plan verification section updated.
