feat: add Worker status section to Servers page

- New WorkerInfo API type + getWorkerStatus() in server-api.ts
- WorkerStatusSection component: online/stale/offline cards
  with instanceId, version, hostname, queues, heartbeat age
- Auto-refresh every 15s
- Register /servers route (SUPER_ADMIN only)
