/**
 * Team Invitation E2E Tests
 *
 * Tests the complete team invitation flow from the user's perspective.
 * These tests verify:
 * 1. Owner can invite staff members
 * 2. Staff receives correct tab permissions (limited access)
 * 3. Invitation accept page shows organization details
 * 4. Password setup creates account and adds to organization
 * 5. Invalid/expired tokens show appropriate errors
 *
 * Prerequisites:
 * - Dev server running on port 9000
 * - Test user with tier3+ subscription (to have multi-staff feature)
