shubhampal24/rack_management ? reverse-engineered prompt

Build me a simple warehouse rack management app that helps track where items are stored and what is available in each rack.

I want a clean frontend where someone can view racks, search for items, add or edit rack details, and see which slots are full or empty. The backend should handle storing the data safely and make it easy to create, update, and remove records. If it helps, also include a way to import the existing Excel data into the app so I can start from what’s already in the file.

Keep the experience straightforward and usable for a warehouse team, with basic validation and clear labels. If anything is unclear from the existing files, inspect the current code and look up current docs online if you need to. Please make it work end to end, so I can run it locally and use it without extra setup headaches.
