Unknown-sir/ironpanel ? reverse-engineered prompt

I want you to build me a full featured VPN and proxy management panel like IronPanel, with a clean dashboard where I can add users, set traffic limits, expiry dates, speed limits, and control which protocols each user can use.

It should let me generate subscription links and QR codes, manage common protocols like OpenVPN, WireGuard, Xray, Hysteria2, MTProto, SSH, and the older ones too if possible. I also need a way to manage multiple nodes or servers from one place, sync users across them, and support a tunnel or relay setup so users keep using the main server address while traffic can be routed through another node behind the scenes.

Please include SSL setup, DNS settings, basic monitoring, health checks, backup and restore, logs, and safe updates. If something depends on current docs or system commands, look them up online if you need to. Make it run as a real server app, not just a mockup, and keep the interface simple enough for day to day admin use.
