- Remove Go dashboard (replaced by Next.js)
- Add API route /api/dashboard: Docker container list, Jaeger
traces, Prometheus metrics, node resources
- Add /dashboard page: React client component with inline SVG
charts (donut, sparkline, gauge), auto-refresh every 15s
- Same dark theme as original Go dashboard
