/**
 * User Support Tickets E2E Tests
 *
 * Tests the support ticket system from the user dashboard perspective.
 * These tests verify that users can:
 * 1. Access the support tab in their dashboard
 * 2. Create new support tickets
 * 3. View their existing tickets
 * 4. Reply to tickets
 *
 * CRITICAL: Tests both NextAuth and auth_token authentication methods
 * to ensure the fix for the dual-auth bug remains in place.
