fix: agent timeouts hid hf-pdocker-01; refresh links and groups

- agent: stats one_shot=True + 20 workers (.192 went 12s -> ~2s);
  /health ignores Dead containers
- server: /containers fetch timeout 10s -> 30s (was silently returning
  [] for the busiest node)
- links page: drop FRIDAY Voice, add Onyx, Guacamole, Synapse Admin,
  n8n, CouchDB; MCPO -> /docs, Trivy -> /healthz, Jellyseerr -> Seerr
- config.json: drop dead gpu-workstation (192.168.86.27)
- groups.json: rebuilt for current container names (14 groups)
- includes earlier uncommitted work (models, styles, ports sorting)
