OpenAI, .net 10, database, demo?

I saw this repo come up in my google search and I have a few questions

1. is there any other AI provider like Ollama are supported by eShop?
2. .net 10 is not mentions in readme.md, so is there any update planned to is supported but readme.md is not updated?
3. which database is used by the app
4. is there any demo link that can show case both user frontend and admin panel?

Start with readme.md and the repository documentation to verify the .NET 10 support status, supported AI providers including Ollama, database choice, and available demo links. Done means resolving the four questions with confirmed information and updating the relevant documentation where it is missing.
