feat(iace): bridge OSHA MD library to pattern engine, body-part-specific lift crush hazards

- M600-M604: lift endstop mitigations (Kriechgeschwindigkeit, Schaltleiste,
  Mindestabstand, Hold-to-run, Trittblech) — cite OSHA + EN ISO identifiers
- HP2100-HP2102: body-part crush patterns for lift family (foot under platform,
  hand/body against fixed structure, leg between lift and lateral structure),
  restricted via MachineTypes filter
- pattern_machinetype_overrides.go: post-load pass fills MachineTypes on 14
  legacy patterns (HP1000 Walzen, HP539 Schweiss, HP545/HP782 Glas,
  HP756/HP757/HP760 Fahrtreppe, HP1400-1402 CNC, HP045/HP049 Pressen,
  HP420-422 Conveyor) to prevent drift on Kistenhubgeraet-style projects

Why: Kistenhubgeraet re-init exposed two gaps — the abstract "Bremse versagt
bei Absenkbewegung" pattern fired but the concrete foot-crush body-part variant
was missing, AND ~10 unrelated patterns fired purely because their RequiredTags
incidentally aligned. Override map avoids touching 1000+ LOC pattern files
that already exceed the soft cap.
