feat(ui): migrate cache_health to shadcn

- @tremor TabGroup/TabList/Tab/TabPanel/TabPanels/Text/Button \u2192 shadcn
  Tabs/TabsList/TabsTrigger/TabsContent + Button.
- @heroicons CheckCircleIcon/XCircleIcon/ClipboardCopyIcon \u2192 lucide
  CheckCircle/XCircle/ClipboardCopy.
- Raw text-gray-* / bg-gray-* / text-green-500 / text-red-500 \u2192 semantic
  tokens (text-muted-foreground/bg-muted/text-foreground/text-emerald-500/
  text-destructive). Status badge uses non-semantic emerald/red because
  health/error is a categorical signal.
- Replace hardcoded indigo primary button gradient with default Button
  (now driven by shadcn primary token).

Gates: TS \u2713 | Build \u2713.
