airlinklabs/panel ? reverse-engineered prompt

Build me an open source game server management panel that feels solid and actually usable for real hosting. I want a web dashboard where admins can create and manage servers, see resource usage, start stop restart servers, watch the live console, browse files, handle backups, and connect over SFTP. It should support multiple nodes, with one main panel talking to daemons on each machine, and the daemon communication should be signed and secure. Add user accounts with permissions, 2FA, scoped API keys, and a simple addon system so features can be extended without changing the core app.

Make it look clean and modern, with a dashboard style UI, and include multi language support if possible. Use the existing docs and current best practices online if you need to, and wire it up so it can run locally and be deployed with a database and environment config.
