🔗 Add Grafana route to Traefik

✅ Added Grafana service and router configuration:
- Service: grafana-cluster → http://influxdb.tailnet-68f9.ts.net:3000
- Router: grafana-ui → Host(grafana.git-4ta.live)
- Health check: /api/health endpoint
- SSL: Cloudflare certificate resolver

🌐 Access URL: https://grafana.git-4ta.live
- Redirects to /login (working correctly)
- Full SSL/TLS support via Cloudflare

Deployed and tested successfully ✅
