/**
* Frontend API Simulation Test
*
* This script simulates how the frontend would interact with the backend APIs
* using the exact same patterns defined in the frontend/src/api structure.
*
* Purpose:
* - Verify frontend API abstraction aligns with backend endpoints
* - Test onboarding flow using frontend API patterns
* - Identify any mismatches between frontend expectations and backend reality
