bfuhrmann/tuctapi ? reverse-engineered prompt

Build me a simple Java backend API that can run locally with Docker and a database. I want the app to start cleanly, connect to the database, and have a few basic endpoints for creating, reading, updating, and deleting records so I can use it as a working starter project.

Please make it easy to run with the existing Maven setup and Docker files, and include whatever database initialization is needed so a fresh setup works without manual steps. If you need to check current docs for anything, go ahead and look them up online.

Keep the code clean and straightforward, with sensible defaults, clear error handling, and a README style setup that would make it easy for someone else to clone the repo and get it running quickly.
