chore: Remove unused code and update module imports

The commit removes the unused `app.controller.ts` and `app.service.ts` files. It also updates the `app.module.ts` file to import the `ListingModule` and remove the `AppController` and `AppService` imports. This cleanup improves the codebase by removing unnecessary files and updating the module imports.
