Build me a self hosted AI powered business intelligence app where people can connect a database or other data source, ask questions in plain English, and instantly get answers as tables, charts, and a short summary. I want a clean web app with a landing page, project and data source management, an AI chat experience that can run SQL behind the scenes, and a dashboard builder where users can add and rearrange KPI cards, charts, and tables. It should also support knowledge base uploads for document search, saved chat history, user management, and settings for choosing the AI model.

Please make it work well in Docker, with a backend API and a modern frontend, and include report export to PDF and presentation format, plus scheduled report delivery through Telegram. If anything needs current library docs or setup details, look them up online and keep the app easy to run locally.
