Build me a Streamlit app for business analytics where I can upload CSV, Excel, JSON, ZIP, or a SQL database and instantly get a clean dashboard with the key numbers, charts, and trends.

I want it to feel like a mini Power BI plus AI helper for business data. The app should profile the data, help clean it, let me transform it, and then show useful insights like sales performance, customer segments, product performance, anomalies, and forecasts. It should also let me ask questions in plain English about the uploaded data and answer from the actual rows. If an AI key is not available, it should still work with a built in fallback.

Please include a report export so I can download a board ready PDF, plus Excel and PowerPoint if possible. Add login and history for datasets, chats, and reports, and a guest mode for trying it quickly. Make the interface polished and easy for a business user, with demo data I can load right away. If you need to look up current docs online, feel free to do that.
