feat: V1 Control Enrichment — Eigenentwicklung-Label, regulatorisches Matching & Vergleichsansicht

863 v1-Controls (manuell geschrieben, ohne Rechtsgrundlage) werden als
"Eigenentwicklung" gekennzeichnet und automatisch mit regulatorischen
Controls (DSGVO, NIS2, OWASP etc.) per Embedding-Similarity abgeglichen.

Backend:
- Migration 080: v1_control_matches Tabelle (Cross-Reference)
- v1_enrichment.py: Batch-Matching via BGE-M3 + Qdrant (Threshold 0.75)
- 3 neue API-Endpoints: enrich-v1-matches, v1-matches, v1-enrichment-stats
- 6 Tests (dry-run, execution, matches, pagination, detection)

Frontend:
- Orange "Eigenentwicklung"-Badge statt grauem "v1" (wenn kein Source)
- "Regulatorische Abdeckung"-Sektion im ControlDetail mit Match-Karten
- Side-by-Side V1CompareView (Eigenentwicklung vs. regulatorisch gedeckt)
- Prev/Next Navigation durch alle Matches
