/**
 * E2E Tests: Profile Industry & Country Persistence
 *
 * These tests ensure industry and country fields:
 * 1. Save correctly from the profile page
 * 2. Persist after page reload
 * 3. Display the correct values in dropdowns
 * 4. Match between signup form values and profile display
 *
 * BUG PREVENTION: Prevents regression of the industry/country not saving issue
 * where country codes (qa, uae, sa) weren't matching full names (Qatar, UAE, Saudi Arabia)
