This fixes a copy-paste error that put both copies of an outer prepreg strip on the C side and none on the A side. - TPC_PRSTR1 copy 2 was placed at z = -177.925 like copy 1, where every neighbouring pair (sandwich, epoxy, and the rotated segments) places its second copy at +177.925. - The strip now sits at +177.925; the world-position census changes from 4 at -177.925 / 2 at +177.925 to the intended 3 / 3. - Found by a TGeo to STEP round-trip study; TGeoManager::CheckOverlaps reports 0 overlaps on TPC either way, so it could not have flagged the coincident pair.
