Build me a full web app that shortens long URLs and sends people to the right place when they open the short link.

I want a simple front end where someone can paste a URL, choose how long it should stay active, either in minutes or days, and get back a short code and a short link. It should also show the original link and let me look up a short code later. If the link has expired, it should stop working and be marked inactive.

Use a React app with TypeScript on the front end and a Java Spring Boot API on the back end with PostgreSQL for storage. Make it work with Docker too, including the database and pgAdmin. The API should validate that the URL is real, create unique short codes, save everything in the database, and redirect from a route like /goto/{shortCode}. If you need to check current docs online while building, go ahead.
