fix(node-traffic): restart remote xray after disabling clients to kill active sessions

Browse source 
When a client's traffic limit is reached on a remote node, the panel pushes
enable=false to that node via UpdateInbound. The node calls RemoveUser on its
local xray, which blocks new connections but leaves any already-established TCP
session alive. The user could continue browsing/downloading until they
disconnected voluntarily.

Fix: after successfully pushing a client disable to a remote node, call
RestartXray on that node. This mirrors what already happens for the local node
when the "Restart Xray on client disable" setting is enabled (default: on),
and ensures active sessions are terminated immediately on all nodes where the
client was disabled.
