calcom/cal.diy ? reverse-engineered prompt

I want to build a self-hosted scheduling application, basically an open-source alternative to Calendly. It should be based on Cal.com, but specifically the community diy version that removes all the enterprise code, so it's 100% MIT-licensed and doesn't need a license key to run.

The main function is for a user to be able to create an account, connect their personal calendar, and get a public booking page. On that page, other people can see their availability and schedule meetings right there.

For the tech stack, let's use Next.js, Tailwind CSS, and Prisma with a PostgreSQL database, since that's what the project is built on. Please set up the entire project structure and handle all the initial configuration. The most important thing is making it easy to deploy, so please containerize the application using Docker so I can run it myself without a complicated setup.
