kalamkarkrushna/Hospital-Management-System ? reverse-engineered prompt

Build me a hospital management web app that feels like a real SaaS product for multiple hospitals.

I want a clean dashboard where staff can log in and manage patients, doctors, appointments, invoices, medicines, lab reports, shifts, inventory, and video call visits. Each hospital should only see its own data, and users should have either admin or staff access with protected pages and permissions. Please include a simple onboarding or register flow for a new hospital, then seed some demo data so the app is usable right away.

Make the UI modern and easy to use on desktop, with search, forms, tables, and basic stats on an insights page. Use a React frontend and a Spring Boot backend with MySQL, and make sure authentication is secure with JWT and session handling that works well in the browser. If you need to check current docs for anything, go look them up online.
