v1.3.1

Changed

• Per-table totals. Replaced the all-time grand-total strip (added in 1.3.0) with a
  totals row at the foot of each dashboard breakdown — By model, By project, and By
  branch now sum their Messages, Tokens, and Cost columns, in the same format as the rows
  above. The All Time card already serves as the grand total, so the separate strip was
  redundant; per-section totals are more useful.
