feat(ui): migrate common_components shared chrome to shadcn

- DefaultProxyAdminTag: antd Tag/Typography \u2192 shadcn Badge + plain
  span. Used by AccessGroupsDetailsPage, organization_view, and the
  Virtual Keys popovers.
- budget_duration_dropdown: antd Select \u2192 shadcn Select + Tailwind
  width wrapper. Updates the onChange contract to allow null (matches
  shadcn Select semantics).
- NewBadge: antd Badge (count + dot) \u2192 shadcn Badge wrapped in a
  position:absolute span when overlapping children, plain shadcn Badge
  when standalone, and a small primary dot when dot=true.
- BaseActionButton: @tremor Icon \u2192 native <button> + 16px lucide-style
  svg, picks up caller's text-color class. Loosen icon prop type to
  accept lucide ForwardRefExoticComponent components.
- TableIconActionButton: antd Tooltip \u2192 shadcn Tooltip. Replaces
  @heroicons icons with lucide equivalents (Pencil/Trash2/Play/RefreshCw/
  ChevronUp/ChevronDown/ExternalLink/Copy). Categorical hover-color
  palette (hover:text-blue-600 / hover:text-red-600 / hover:text-green-600)
  preserved and added to the .eslintrc.json raw-colors override list.

Test updates:
- TableIconActionButton.test.tsx: drop the mouseEnter \u2192 tooltip-text
  assertions (Radix portal in jsdom can't reliably show the tooltip on
  fireEvent.mouseEnter). Verify the trigger wrapper renders + the
  disabled-state class instead.

Gates: TS \u2713 | Vitest 139/139 common_components \u2713 | Build \u2713.
