"""
E2E Full Pipeline Test — dev.performancewest.net

Tests the complete CRTC order flow:
1. Fill order form with AMB location selection
2. Submit order → verify PG record + ERPNext Sales Order
3. Stripe checkout redirect
4. Simulate payment completion → verify advance to Awaiting Funds
5. Simulate balance.available → verify advance to Client Selection + email
6. Verify portal setup page loads
7. Verify DID search endpoint works
8. Verify setup-confirm endpoint works

Run via workers container on prod host.
