neoauroraproject/hmpanel ? reverse-engineered prompt

Build me a web based management panel for 3x ui that makes it much easier to run a VPN business from one place.

I want a clean admin dashboard where I can see server status, client usage, and basic infrastructure monitoring at a glance. It should let me manage multiple 3x ui panels, add resellers with different permission levels, set traffic and client limits, and handle clients in bulk. Please include support for assigning one client across multiple inbounds, since that’s important for how we run things.

I also need solid backup and restore tools, both in the web app and from a simple command line tool, so I can download, upload, and restore the database without pain. If there’s anything unclear in the docs, feel free to look up current references online and make sensible choices. Make it feel polished, reliable, and built for production use.
