feat: Phase 3 — RAG-Anbindung fuer alle 18 Dokumenttypen + Vendor Contract Review

Migrate queryRAG from klausur-service GET to bp-core-rag-service POST with
multi-collection support. Each of the 18 ScopeDocumentType now gets a
type-specific RAG collection and optimized search query instead of the
generic fallback. Vendor-compliance contract review now uses LLM + RAG
for real analysis with mock fallback on error.
