Vegiveera/databricks-genie-workbench ? reverse-engineered prompt

Build me a Databricks app called Genie Workbench that helps people create, score, and improve Genie Spaces. I want a simple web app with a clean dashboard where users can start from business requirements, connect Unity Catalog data sources, run a quick quality check, and then launch an auto optimize flow to improve the space over time.

The app should keep track of past scans, starred spaces, sessions, and optimization status, and it should show useful results in a friendly way with charts, scores, and readable summaries. Please include a backend API, a React front end, and the Databricks auth and deployment setup needed for it to run inside Databricks Apps. If helpful, use the current docs online so the deployment and permissions are done the right way.

Also make sure there is a clear install and deploy path, sample demo data if needed, and sensible defaults so someone can get it running without having to understand every Databricks detail first.
