Fix a second identity-merging bug: replace (MW,pI)-string protein grouping with an explicit real-molecule identity, and correct pI for 5 of 13 proteins (Trastuzumab, Omalizumab, Adalimumab, a TUR01/adalimumab-biosimilar row, a bispecific stated in its source paper). Previously up to 4 different real antibodies were silently pooled into one fake protein via colliding placeholder pI values.
Replace with audited BioFormBench-Real (49 rows, sourced) and new BioFormBench-Marketed (165 rows, 80 sequenced antibodies); remove dev scaffolding and unsourced placeholder data
