Build me the Getszy app as a simple full stack website.

I want a clean modern interface, with the main frontend wired up to the backend so the app actually works end to end. Please use the existing project structure and make sure the important flows are hooked up, including the routes and any frontend calls that are already implied by the codebase. If there’s any missing piece or outdated code, bring it up to date and make it work nicely.

Keep it practical and polished, with sensible loading states, error handling, and basic responsiveness. If you need to check current docs or best practices for anything, go ahead and look them up online. Also make sure the project runs cleanly from the root with a simple setup and build process.
