Rithvik-v2/expense-analyser ? reverse-engineered prompt

Build me a simple web app for tracking and analyzing expenses. I want to be able to add expense entries, store them in a database, and see a clear summary of where my money is going. The app should have a clean page for entering expenses, a page or section that shows the saved records, and some basic analysis or prediction using the included model file if that makes sense. Please make it easy to use, with a few straightforward templates and a polished but simple layout.

If anything is unclear, inspect the existing Python files and connect the app so the database, saved model, and pages all work together. Keep it lightweight and practical, and use current docs online if you need to. I mainly want a working expense analysis tool that feels finished and can be run locally without a lot of setup.
