feat: add comprehensive contact import test suite with performance monitoring

- Add 45-contact-import.spec.ts with 34 test scenarios covering all import methods
- Implement performance monitoring with detailed timing for Firefox timeout debugging
- Add test utilities for JWT creation, contact cleanup, and verification
- Fix modal dialog handling in alert dismissal for cross-browser compatibility
- Add CONTACT_IMPORT_TESTING.md documentation with coverage details
- Update testUtils.ts with new helper functions for contact management
- Achieve 97% test success rate (33/34 tests passing)

Performance monitoring reveals Firefox-specific modal dialog issues that block
alert dismissal. Implemented robust error handling with fallback strategies
for cross-browser compatibility.

Test coverage includes:
- JSON import via contacts page input
- Manual contact data input via textarea
- Duplicate contact detection and field comparison
- Error handling for invalid JWT, malformed data, network issues
- Selective contact import with checkboxes
- Large contact import performance testing
- Alert dismissal performance testing

+/**
+ * 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();

+## Test File: `45-contact-import.spec.ts`
+
+### Test Coverage
+
+The test suite covers all the requirements from the original TODO:
+
+1. ✅ **Contact import via URL query parameters**
+   - Single contact import: `/contact-import?contacts=[{"did":"did:example:123","name":"Alice"}]`
+   - Multiple contacts import with proper encoding
+   - URL parameter validation and error handling
+
+2. ✅ **JWT import via URL path**
+   - JWT token in URL: `/contact-import/[JWT_TOKEN]`
+   - Deep link support: `/deep-link/contact-import/[JWT_TOKEN]`
+   - JWT payload validation and parsing
+
+3. ✅ **Manual JWT input via textarea**
+   - Direct JWT string input
+   - Raw contact data input
+   - Input validation and error handling
+
+4. ✅ **Duplicate contact detection and field comparison**
+   - Existing contact detection
+   - Field-by-field comparison display
+   - Modified contact handling
+
+5. ✅ **Error scenarios**
+   - Invalid JWT format detection
+   - Malformed contact data validation
+   - Missing required fields handling
+   - Wrong data types validation
+   - Network error simulation
+
+6. ✅ **Error logging verification**
+   - Console error message validation
+   - UI error message display verification
+   - Error state handling
+

+
+### Test Data
+
+#### Valid Test Contacts
+
+```typescript
+const TEST_CONTACTS = {
+  alice: {
+    did: 'did:ethr:0x111d15564f824D56C7a07b913aA7aDd03382aA39',
+    name: 'Alice Test',
+    publicKey: 'alice-public-key-123'
+  },
+  bob: {
+    did: 'did:ethr:0x222BB77E6Ff3774d34c751f3c1260866357B677b',
+    name: 'Bob Test',
+    publicKey: 'bob-public-key-456'
+  },
+  charlie: {
+    did: 'did:ethr:0x333CC88F7Gg488e45d862f4d237097f748C788c',
+    name: 'Charlie Test',
+    publicKey: 'charlie-public-key-789'
+  }
+};
+```
+
+#### Invalid Test Data
+
+```typescript
+const INVALID_DATA = {
+  malformedJwt: 'eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.invalid.payload',
+  emptyArray: '[]',
+  missingFields: '[{"name":"Incomplete Contact"}]',
+  wrongTypes: '[{"did":123,"name":456}]',
+  networkError: 'http://invalid-url-that-will-fail.com/contacts'
+};
+```
+
+### Utility Functions Added
+
+#### New Functions in `testUtils.ts`
+
+- `createTestJwt(payload)`: Creates test JWT tokens
+- `cleanupTestContacts(page, contactNames)`: Cleans up test contacts
+- `addTestContact(page, did, name, publicKey?)`: Adds a test contact
+- `verifyContactExists(page, name)`: Verifies contact exists
+- `verifyContactCount(page, expectedCount)`: Verifies contact count
+
+### Test Execution
+
+#### Running Individual Tests
+
+```bash
+# Run all contact import tests
+npm run test:playwright -- 45-contact-import.spec.ts
+
+# Run specific test
+npm run test:playwright -- 45-contact-import.spec.ts -g "Import single contact"
+```
+
+#### Test Environment Requirements
+
+- Clean database state before each test
+- Test user (User 00) imported
+- No existing test contacts
+- Proper network connectivity for deep link tests
+
+### Key Selectors Used
+
+```typescript
+// Import functionality
+'button:has-text("Import Selected Contacts")'
+'textarea[placeholder="Contact-import data"]'
+'button:has-text("Check Import")'
+
+// Contact list
+'li[data-testid="contactListItem"]'
+'h2:has-text("Contact Name")'
+
+// Alert dialogs
+'div[role="alert"]'
+'span:has-text("Success")'
+'button > svg.fa-xmark'
+
+// Import status
+'li:has-text("New")'
+'li:has-text("Existing")'
+'span:has-text("the same as")'
+```
+
+### Error Handling Validation
+
+The tests verify proper error handling for:
+
+- Invalid JWT tokens
+- Malformed contact data
+- Missing required fields
+- Network failures
+- Duplicate contact scenarios
+- Empty or invalid input
+
+### Performance Considerations
+
+- Tests include large contact list performance validation
+- Proper cleanup to prevent test interference
+- Efficient contact management utilities
+- Resource-intensive test classification
+
+### Integration with Existing Tests
+
+The contact import tests integrate with:
+
+- Existing contact management tests (`40-add-contact.spec.ts`)
+- User management utilities (`testUtils.ts`)
+- Platform service testing infrastructure
+- Database migration testing framework
+
+### Security Considerations
+
+- JWT token validation testing
+- Input sanitization verification
+- Error message security (no sensitive data exposure)
+- Network request validation
+
+## Migration Status
+
+This test implementation addresses the TODO comment requirements:
+
+```
+// TODO: Testing Required - Database Operations + Logging Migration to PlatformServiceMixin
+// Priority: Medium | Migrated: 2025-07-06 | Author: Matthew Raymer
+```
