Ricardolv/aiup-petclinic — reverse-engineered prompt

Build me this AIUP PetClinic demo as a complete working app from the specs in the docs folder. I want a small web app for a veterinary clinic, with the screens, flows, and data model driven by the use case docs, the entity model, and the UI flow specs, not guessed from a one line prompt.

Please use the existing Maven project and finish it so it runs locally, has the database setup and migrations in place, and includes solid automated tests that verify the behavior against the specs. The app should have a basic welcome experience and clear navigation, then whatever full set of clinic features the docs call for.

Keep the docs as the source of truth, and make the code, tests, and any missing wiring match them closely. If something in the specs is unclear, choose the simplest interpretation and leave a short note in the code or docs. You can look up current framework docs online if needed.
