smartcar/starter-app-react-node ? reverse-engineered prompt

Build me a simple web app that uses Smartcar so people can connect their vehicle, see their car data, and disconnect it if they want.

I want a React frontend and a Node Express backend, with Smartcar Connect working end to end. After someone signs in with their car, the app should show a clean dashboard with the vehicle details and whatever data is enabled in the configuration, like mileage, location, tire pressure, VIN, battery info, charging status, and other health or EV stats. It should also support actions where available, like locking or unlocking, starting or stopping charge, and setting charge limits.

Please include the four sample modes from the README for auto insurance, energy and utilities, car sharing, and roadside assistance, with one as the default. Make it easy to switch which vehicle properties are shown through a config file, and make sure the auth flow and backend token handling are set up correctly. If you need current Smartcar docs for anything, look them up online.
