feat(ai-sdk): order the hazard log by ISO 12100 hazard group

ListHazards returned hazards in pattern-firing order, which reads as a jumble.
Sort by EN ISO 12100 hazard group (A. Mechanisch, B. Elektrisch, C. Thermisch,
D. Pneumatik/Hydraulik, E. Laerm, F. Ergonomie, G. Stoffe, H. Software/Steuerung,
I. Cyber, J. KI), stable within a group. Matches the frontend CATEGORY_LABELS.
