feat(iace): CE-Flag auf Komponenten + AIAG-VDA Action Priority (AP)

CE-Flag:
- Toggle "Bereits CE-gekennzeichnet" im ComponentForm
- ce_marked Boolean auf Component (via metadata JSONB, kein DB-Change)
- Hinweis "(Nur Schnittstellen bewerten)" im Formular

AIAG-VDA Action Priority:
- CalculateAP(S,O,D) → H/M/L nach AIAG-VDA FMEA Handbuch 2019
- AP-Spalte in FMEA-Worksheet: H=rot, M=gelb, L=grün
- Ergänzt (nicht ersetzt) die bestehende RPZ-Berechnung
