/**
 * End-to-End Contact Management Tests
 * 
 * Comprehensive test suite for Time Safari's contact management and gift recording features.
 * Tests run sequentially to avoid state conflicts and API rate limits.
 * 
 * Test Flow:
 * 1. Contact Creation & Verification
 *    - Add contact using DID
 *    - Verify contact appears in list
 *    - Rename contact and verify change
 *    - Check contact appears in "Record Something" section
 * 
 * 2. Gift Recording Flow
 *    - Generate unique gift details
 *    - Record gift to contact
 *    - Verify gift confirmation
 *    - Check gift appears in activity feed
 * 
 * 3. Contact Import/Export Tests
 *    - Copy contact details to clipboard
 *    - Delete existing contact
 *    - Import contact from clipboard
 *    - Verify imported contact details
 * 
 * Test Data Generation:
 * - Gift titles: "Gift " + 16-char random string
 * - Gift amounts: Random 1-99 value
 * - Contact names: Predefined test values
 * - DIDs: Uses test accounts (e.g., did:ethr:0x000...)
 * 
 * Key Selectors:
 * - Contact list: 'li[data-testid="contactListItem"]'
 * - Gift recording: '#sectionRecordSomethingGiven'
 * - Contact name: '[data-testid="contactName"] input'
 * - Alert dialogs: 'div[role="alert"]'
 * 
 * Timeouts & Retries:
 * - Uses OS-specific timeouts (longer for Linux)
 * - Implements retry logic for network operations
 * - Waits for UI animations and state changes
 * 
 * Alert Handling:
 * - Closes onboarding dialogs
 * - Handles registration prompts
 * - Verifies alert dismissal
 * 
 * State Requirements:
 * - Clean database state
 * - No existing contacts for test DIDs
 * - Available API rate limits
 * 
 * @example Basic contact addition
 * ```typescript
 * await page.goto('./contacts');
 * await page.getByPlaceholder('URL or DID, Name, Public Key')
 *   .fill('did:ethr:0x000...., User Name');
 * await page.locator('button > svg.fa-plus').click();
 * ```
