style(banner): give the dispatch banner room to read as an invitation

Three changes to <LatestDispatchBanner>:

- Padding: 22/26 → 28/26 — extra top weight stops the eyebrow + title
  feeling stuck to the card edge.
- Excerpt: the previous nowrap + text-overflow: ellipsis clamp was
  truncating mid-sentence. Replaced with -webkit-line-clamp: 2 so a
  real sentence (and a half) renders. line-height 1.55, font-size
  bumped 12 → 13 to match the longer reading rhythm.
- Kind pill next to the title, same pattern as the home-page dispatch
  byline pill: 9px tracked uppercase, 2/8 padding, 3px radius, kind-
  pigment-tinted background at 10% opacity. Wraps below the title on
  narrow widths via flex-wrap on .b-title-row.

Banner margin-bottom (set on /roadmap.astro) stays at 56px for now;
the spec's reduction to 40px is conditional on the In motion strip
landing, which is the commit after next.
