fix(frontend): shrink dashboard percent text and surface the unfinished arc

Two follow-up tweaks to the dashboard gauges:
- AD-Vue scales the percent text from the SVG, not from :width, so
  the 90px gauges still rendered the number at ~27px. Pin
  .ant-progress-text to 14px via :deep() and trim the gauge to 70px
  (60px on mobile) so the whole card stays compact.
- The default trail (rgba(0,0,0,0.06) / rgba(255,255,255,0.08)) was
  invisible on the light-theme card. Pass an explicit
  rgba(128,128,128,0.25) trail-color so the unfinished portion is
  visible under both light and dark themes.
