feat(nodes): per-node client IP attribution for IP-limit

Record each panel's own Xray IP observations under its panelGuid and merge each node's guid-keyed report on the master, so the panel can tell which node a client IP is connecting through (the flat inbound_client_ips union is pushed back to every node and cannot attribute). Adds the NodeClientIp model + migration, the clientIpsByGuid endpoint and node-sync merge, node-name labels in the client IP log, and cleanup on node deletion.
