style(runs): polish list surfaces, toggles, and accessibility

- run card: solid bg-panel at rest instead of bg-panel/80 (opacity
  shift on hover was backwards)
- column header: mb-3 to match inter-card gap
- lifecycle tag: 10px → 11px (below readable threshold for uppercase)
- additions/deletions: tabular-nums so large counts don't jitter
- view toggle: add a bg-overlay active state so the active view is
  not purely a hue shift; wrap in role="group" with aria-pressed on
  each button
- search + repo select: add aria-label and name attributes
