feat(web): restore the process-row polish on the grouped work details

* feat(web): restore the process-row polish on the grouped work details

The sweep highlight, shared row colors, expanded-row spacing, and the
12–24px font-size range were developed against the pre-revert work-details
implementation. Re-apply them to the grouped implementation that replaced it.

- TextShimmer keeps its active-driven span and now paints a masked sweep
  overlay in the theme's `--dsw-alias-label-shimmer` color, so the base text
  inherits the caller's color and hover changes.
- DisclosureRow owns the row color: tertiary at rest, secondary on hover,
  with glyphs, titles, and summaries inheriting it; tool, skill, command,
  reasoning, and workflow rows drop their own hover darkening.
- ChatView spaces process rows 8px apart and keeps 16px beside Assistant
  responses; the grouped header sits 8px above its first member.
- The Settings font-size stepper accepts 12–24px, and the grouped header's
  leading box and glyph scale with the content font-size delta.
