fix(frontend): address review nits on the markdown prose fix

- default `GfmMarkdown` to the `sm` stack rather than `xs`: the AI-agent tool
  Message pane takes the default and has no ancestor font size, so `xs` left it
  smaller than its own label. The group note, whose wrapper is `text-2xs`, opts
  down explicitly.
- regenerate `static/tailwind_full.css`, which raw apps are served and which
  still carried the deleted list rules.
- correct the marker-color rationale: the typography config already maps markers
  to tertiary, so the rule steps them up rather than rescuing them.
