/**
 * Administrative Features E2E Test Suite - Agent D
 * 
 * Comprehensive end-to-end testing for administrative and operational systems
 * Focus Areas:
 * - Certificate generation and reporting
 * - Mass communication systems  
 * - Data integration (Google Sheets)
 * - Import/export functionality
 * - Administrative workflows
 * 
 * Requirements:
 * - Use MCP Playwright tools for browser automation
 * - Test with GNOME session display integration
 * - Stage testing at https://upskill-staging.measurequick.com
 * - Use test accounts: test_trainer/TestTrainer123!, test_master/TestMaster123!
 * - Include WordPress error detection before each test
