 * Test Setup Intent Pattern for 3DS Authentication
 * 
 * This script tests the new /api/subscription/setupCard endpoint
 * to verify card pre-authentication before subscription creation.
 * 
 * Usage:
 *   node test_setup_intent.js
 * 
 * Test Cards:
 *   - 4242424242424242: No 3DS (immediate success)
 *   - 4000000000003220: 3DS required
 *   - 4000000000000341: Always fails
