adminsyspro/proxcenter-ui — reverse-engineered prompt

Build me a modern self hosted web app like ProxCenter for managing Proxmox from one place. I want a clean dashboard where I can connect multiple Proxmox VE clusters, see their nodes and virtual machines, monitor health and resources, and manage basic cluster operations without jumping between different Proxmox screens.

It should feel polished and admin friendly, with a single pane of glass layout, navigation for clusters, nodes, VMs, storage, backups, monitoring, and settings. Include support for Proxmox VE 8 and 9, connection settings for the Proxmox API on port 8006, and an option for running behind a reverse proxy so failover doesn’t switch to internal node IPs.

Make it easy to run with Docker Compose on one port, around 3000, with a sample env file and simple install or start instructions. Community features should work without a license, and leave room for enterprise style features like workload balancing, alerts, reports, and backup server management later. Look up current Proxmox API docs online if needed.
