Previously seenNodes used only the node name as the dedup key, causing
independent servers that happen to share a default node name (e.g. "pve")
to hide each other's charts.
Fix: /api/{server_id}/nodes now also returns cluster_id — the actual
Proxmox cluster name for clustered servers, or "standalone-{server_id}"
for single-node servers. The dashboard deduplicates by
"cluster_id::node_name", so:
- nodes in the same cluster → deduped correctly (shown once)
- nodes on independent servers with the same name → both shown
