/**
 * Chat Image E2E Test with Real Browser and Mock Model Server
 *
 * This test verifies the complete flow:
 * 1. Browser opens frontend at http://localhost:3000
 * 2. User uploads an image and sends a message
 * 3. Frontend sends request to backend at http://localhost:8000
 * 4. Backend processes the image and sends to model
 * 5. Mock model server captures the request and verifies image_url format
 *
 * Prerequisites:
 * 1. Frontend running at http://localhost:3000
 * 2. Backend running at http://localhost:8000
 * 3. Mock model server running at http://localhost:9999
 *    Start with: npx ts-node frontend/e2e/utils/mock-model-server.ts
