serenity-is/Serenity — reverse-engineered prompt

I want this turned into a working starter business app using the Serenity platform, so I can run it locally and see the full flow in action. Please set it up the way this repo expects, make sure it builds cleanly, and give me a basic admin style app with login, navigation, data grids, forms, and normal create read update delete screens for at least one simple sample data module so I can understand how the platform is meant to be used.

Keep it close to the built in Serenity and Serene approach from the repo, not a custom rewrite. I want something that shows the usual patterns for a data heavy internal app, with the backend services and the TypeScript frontend wired together and easy to extend later.

Please also leave the project in a state where I can just install what is needed, run it, open localhost, and start clicking around. If anything in the repo has changed, look up the current Serenity docs online and use the recommended setup.
