"""
Integration tests for vendor onboarding API endpoints.

Tests cover:
1. Onboarding status retrieval
2. Step 1: Company profile setup
3. Step 2: Letzshop API configuration
4. Step 3: Product import configuration
5. Step 4: Order sync (mocked)
6. Step order validation (can't skip ahead)
7. Onboarding completion flow
