feat(iace): integrate ISO 12100 machine risk model with 4-factor assessment

Add dual-mode risk engine: legacy S×E×P (avoidance=0) and ISO mode S×F×P×A
(avoidance>=1) with new thresholds (low/medium/high/very_high/not_acceptable).

- 150+ hazard library entries across 28 categories incl. physical hazards
  (mechanical, electrical, thermal, pneumatic/hydraulic, noise/vibration,
  ergonomic, material/environmental)
- 160-entry protective measures library with 3-step hierarchy validation
  (design → protective → information)
- 25 lifecycle phases, 20 affected person roles, 50 evidence types
- 10 verification methods (expanded from 7)
- New API endpoints: lifecycle-phases, roles, evidence-types,
  protective-measures-library, validate-mitigation-hierarchy
- DB migrations 018+019 for extended schema
- Frontend: 4-slider risk assessment, hierarchy warnings, measures library modal
- MkDocs wiki updated with ISO mode docs and legal notice (no norm text)

All content uses original wording — norms referenced as methodology only.
