khalmam/erpnext-saas-controller ? reverse-engineered prompt

Build me a simple SaaS controller for ERPNext that helps me manage customer sites from one place.

I want a web app that can keep track of tenants, create and organize new ERPNext instances, and show basic status for each one so I can see what is running, what needs attention, and what has been stopped. It should feel like an admin dashboard, with a clean homepage, a list of sites, and simple actions to add, view, and manage them.

Please make it easy to run locally and keep the project organized so I can extend it later. If you need to check current setup details or best practices, look up the latest docs online. Use the existing project structure where it makes sense, and keep the interface straightforward and practical rather than fancy.
