yHoney-72/flashcart-backend ? reverse-engineered prompt

Build me a clean Java backend project that I can run with Maven. I want the app scaffolded properly, with a simple starting API, a health check, sensible package structure, and a few basic tests so I know it works.

Please make it easy to run locally with the Maven wrapper, and keep the code organized so it can grow into a real backend later. If you need to check current library or framework setup details, look up the latest docs online and choose the simplest stable approach.

I also want the usual project basics in place, like clear config, helpful error handling, and anything needed so the project feels ready for a real team to start building on. Keep it straightforward and production friendly, but don’t overcomplicate it.
