fix(iace): roadmap group B — citation/license/tier cleanup
C1: drop the misleading OSHA §1910.212(a)(5) fan-guard citation from M602
(overhead lift clearance) — EN 349 + EN ISO 13854 already cover it.
C2: frame M237's 25/500 mm as Richtwerte to be determined per EN ISO 13854
(single factual values in prose are facts, not table reproduction — but
keep the conservative caveat).
C3: keep ergonomic W=2 deliberately and document why — ESAW ranks it the most
frequent non-fatal mode (24.7%) but that population doesn't transfer to an
acute machine point-hazard; the machine GT governs.
