Build me a horse racing management web app with a separate frontend and backend. I want it to feel like a simple admin system where staff can manage horse racing information, view records, add new data, edit existing data, delete wrong entries, and generally keep everything organized from a browser.

Use the existing project split, with the frontend in its own folder and the backend as a Spring Boot service. Make sure the frontend can talk to the backend through clear API endpoints. Keep the screens clean and easy to use, with forms, tables, and basic navigation so someone can understand it without training.

Please set it up so I can run the frontend with npm install then npm start or npm run dev, and open the backend in IntelliJ or Eclipse as a normal Maven or Gradle Spring Boot project. If anything is missing, fill in sensible basics and make sure the full app runs locally.
