fix(iace): resolve M-ID collisions for electrical/pressure patterns

Browse Source 
6 supplementary measures (M410-M420) were silently overwritten by
metalworking duplicates in measureByID lookups, so robot-cell electrical
patterns resolved to chip-extraction/cleaning fallbacks instead of
equipotential bonding, creepage, EMC, or hose-burst protection. Rename
supplementary IDs to M475-M480 and rewire 13 affected pattern references
in robot_cell + robot_cell_ext.

HP1640 (direct contact with live parts, GT 2.2): priority 98->99, drop
RequiredEnergyTags gate so it fires in robot cells without an electrical
tag, expand mitigations to 5 concrete TRBS 2131 / IEC 60204-1 / EN 61140
measures (basic protection, double insulation, earthing, insulation
monitoring, equipotential bonding) — was previously losing to HP1688
even though HP1688 describes a different scenario.

HP1688 (touch voltage from potential differences): priority 98->96 so it
no longer outranks HP1640 for the direct-contact case; mitigations
expanded from M410-only to 4 concrete electrical measures.

Add regression tests pinning HP1640 contact-protection resolution and
M475 = Potentialausgleich. Existing TestGetProtectiveMeasureLibrary_-
UniqueIDs now actually enforces uniqueness (previously masked by
last-wins map override).
