fix: rebalance Posts list column widths (v0.13.7)

35% title + 255px fixed PRAB cols left ~50px per auto column.
Replace with a balanced budget across all columns so Author,
Categories, Tags, and Date all get enough room to render horizontally:
  title 22%, author 6%, categories 7%, tags 9%, date 8%,
  writing_model/image_model 85px each, cost 50px, peptide_topics 75px
