feat(iace): Betriebszustand-Traceability auf Hazards + Mitigations

Hazards zeigen jetzt farbige Badges mit den Betriebszustaenden die sie
ausgeloest haben (z.B. "Wartung", "Not-Halt"). Mitigations erben die
States ihrer verknuepften Hazards.

Backend: OperationalStates im Function-Feld encodiert (kein DB-Schema),
beim Lesen als operational_states[] JSON-Feld zurueckgegeben.
Frontend: Indigo-Badges in HazardTable + MitigationCard.
