Description

Unless I missed it somewhere, there doesn't seem to be a way to set the trustProxy setting. Per the below source code:

dockge/backend/dockge-server.ts

Lines 459 to 469 in e31f766

	if (await Settings.get("trustProxy")) {
	const forwardedFor = socket.client.conn.request.headers["x-forwarded-for"];
	if (typeof forwardedFor === "string") {
	return forwardedFor.split(",")[0].trim();
	} else if (typeof socket.client.conn.request.headers["x-real-ip"] === "string") {
	return socket.client.conn.request.headers["x-real-ip"];
	}
	}
	return clientIP.replace(/^::ffff:/, "");
	}

if the trustProxy setting is not set, the X-Forwarded-For and X-Real-Ip headers will not be respected which is needed when a reverse proxy is used.

I set the trustProxy setting in the Sqlite3 database manually and the real IP's were used correctly so just a way to set the trustProxy setting with an environment variable and/or a setting in the web UI is needed.

INSERT INTO setting (key,value,type) VALUES('trustProxy', 'true', 'general');

👟 Reproduction steps

Use a reverse proxy and login into Dockage and the logs will report the private IP address of the Docker container instead of the real IP address of the user.

👀 Expected behavior

A way to set the trustProxy setting with an environment variable and/or a setting in the web UI so that the X-Forwarded-For and X-Real-Ip headers will be respected when using a reverse proxy.

😓 Actual Behavior

The private IP address 172.19.0.1 of the docker container is reported instead of the real IP:
