gopro2027/ArduinoAirSuspensionController ? reverse-engineered prompt

Build me a complete open source air suspension controller system for a car, with the ESP32 firmware as the main part, plus the wireless controller code and a simple mobile app. I want it to let me raise and lower the car, save presets, show pressure readings, and control the manifold from a touchscreen or phone. It should feel like a polished DIY replacement for expensive air suspension kits, with a clean interface and clear status on the screen.

Please make the project easy to set up for someone building it at home, with straightforward config values for things like Bluetooth pairing and sensor setup. If there are any parts that depend on current docs or library changes, look up the latest info online and use the best approach. Also include the pieces needed for the small screen display so it can show useful icons and readouts clearly.
