feat: BetrVG-Compliance-Modul — Obligations, Konflikt-Score, Frontend

1. BetrVG Obligations (JSON V2): 12 Pflichten basierend auf §87, §90, §94, §95, §99, §111
   - BAG-Rechtsprechung referenziert (M365, SAP, Standardsoftware)
   - Applicability: DE + >=5 Mitarbeiter
2. Betriebsrats-Konflikt-Score (0-100): Gewichtete Formel aus 8 Faktoren
   - Ueberwachungseignung, HR-Bezug, Individualisierbarkeit, Automation
   - Escalation-Trigger: Score>=50 ohne BR → E2, Score>=75 → E3
3. Frontend: 3 neue Intake-Felder (Monitoring, HR, BR-Konsultation)
   - BR-Konflikt-Badge in Use-Case-Liste + Detail-Seite
   - Farbcodierung: gruen/gelb/orange/rot
