shenaba/2s-ui ? reverse-engineered prompt

Build me a clean web admin panel for sing-box that lets me manage proxy and VPN servers from one place. I want a simple multilingual dashboard where I can add and edit clients, set traffic limits and expiry dates, generate share links, QR codes, and subscriptions, and see live usage and online status.

It should support common protocols like VLESS, VMess, Trojan, Shadowsocks, Hysteria2, TUIC, and the other sing-box options mentioned in the README. I also want routing rules, traffic statistics, a way to manage multiple nodes together, automatic HTTPS setup with certificates, and basic notifications for important events like logins, clients, and node health.

Please make the UI polished, with dark and light themes, and keep it easy to use on desktop and mobile. If you need to check current sing-box or certificate setup details, look up the latest docs online.
