Node settings page: WebSocket connection string uses internal bind port instead of location.host

[lijunle-bot]

Bug

gatewayWsUrl() in page-nodes.js (L26-30) constructs the WebSocket connection string using gon.get("port") — the server's internal bind port from config. When behind a reverse proxy or tunnel, this produces a wrong URL like wss://example.com:38309/ws instead of wss://example.com/ws.

function gatewayWsUrl() {
    var proto = location.protocol === "https:" ? "wss:" : "ws:";
    var port = gon.get("port") || location.port;  // ← uses server bind port
    var host = location.hostname;
    return `${proto}//${host}${port ? `:${port}` : ""}/ws`;
}

Every other WebSocket connection in the codebase correctly uses location.host:

File	Line	URL Construction
ws-connect.js	L44	`${proto}//${location.host}/ws/chat`
page-settings.js	L1874	`${wsProtocol}//${window.location.host}/graphql`
page-terminal.js	L805	`${proto}//${location.host}/api/terminal/ws`

Fix

Align with the rest of the codebase:

function gatewayWsUrl() {
    var proto = location.protocol === "https:" ? "wss:" : "ws:";
    return `${proto}//${location.host}/ws`;
}

location.host already includes the correct hostname and port (or omits it when it's the default 443/80).
