/**
 * Contact Import End-to-End Tests
 * 
 * Comprehensive test suite for Time Safari's contact import functionality.
 * Tests cover all import methods, error scenarios, and edge cases.
 * 
 * Test Coverage:
 * 1. Contact import via URL query parameters
 * 2. JWT import via URL path
 * 3. Manual JWT input via textarea
 * 4. Duplicate contact detection and field comparison
 * 5. Error scenarios: invalid JWT, malformed data, network issues
 * 6. Error logging verification
 * 
 * Import Methods Tested:
 * - URL Query: /contact-import?contacts=[{"did":"did:example:123","name":"Alice"}]
 * - JWT Path: /contact-import/[JWT_TOKEN]
 * - Manual Input: Textarea with JWT or contact data
 * - Deep Link: /deep-link/contact-import/[JWT_TOKEN]
 * 
 * Test Data:
 * - Valid DIDs: did:ethr:0x... format
 * - Test contacts: Alice, Bob, Charlie with various properties
 * - Invalid JWTs: Malformed, expired, wrong signature
 * - Malformed data: Missing fields, wrong types, empty arrays
 * 
 * Key Selectors:
 * - Import button: 'button:has-text("Import Selected Contacts")'
 * - JWT textarea: 'textarea[placeholder="Contact-import data"]'
 * - Check import button: 'button:has-text("Check Import")'
 * - Contact list items: 'li[data-testid="contactListItem"]'
 * - Alert dialogs: 'div[role="alert"]'
 * 
 * Error Handling:
 * - Invalid JWT format detection
 * - Malformed contact data validation
 * - Network error simulation
 * - Duplicate contact field comparison
 * - Error message verification
 * 
 * State Management:
 * - Clean database state before each test
 * - Contact cleanup after tests
 * - User state management
 * 
 * @example Basic URL import test
 * ```typescript
 * await page.goto('./contact-import?contacts=[{"did":"did:test:123","name":"Test User"}]');
 * await expect(page.locator('li', { hasText: 'New' })).toBeVisible();
 * await page.locator('button:has-text("Import Selected Contacts")').click();
 * ```
