Fix migration dates, add multi-platform testing infrastructure, and organize docs

Migration Date Corrections:
- Update all migration TODO comments to use correct date: 2025-07-06
- Add proper TypeScript type declarations for $route and $router in DeepLinkErrorView
- Fix template property references to use $route instead of route

Multi-Platform Testing Infrastructure:
- Add comprehensive multi-platform testing requirements for migrations
- Update component migration template with platform testing requirements
- Establish sign-off requirements for web, desktop, and mobile platforms
- Document expected outcomes and validation procedures

Migration Testing Organization:
- Create docs/migration-testing/ folder for testing documentation
- Move TESTING_CONTACTIMPORT.md from project root to migration-testing/
- Relocate all migration-checklist-*.md files to migration-testing/
- Add comprehensive README.md with organization guidelines
- Update file references in components and TODOs
- Establish naming conventions and quality standards

Files added:
- docs/migration-testing/README.md
- docs/migration-testing/TESTING_CONTACTIMPORT.md
- docs/migration-testing/migration-checklist-ContactImportView.md
- docs/migration-testing/migration-checklist-MembersList.md

Files modified:
- src/views/ContactImportView.vue (date correction)
- src/components/MembersList.vue (date correction, reference path update)
- src/views/DeepLinkErrorView.vue (date correction, Vue router types)
- docs/migration-templates/component-migration.md (multi-platform requirements)

Files moved:
- TESTING_CONTACTIMPORT.md → docs/migration-testing/
- docs/migration-checklist-*.md → docs/migration-testing/

This establishes comprehensive testing infrastructure for all future migrations
with proper organization and multi-platform validation requirements.

+# ContactImportView.vue Testing Guide
+
+## Quick Testing Setup
+- Web server running at: `http://localhost:3000`
+- Migration completed: 2025-07-06
+- Component: `src/views/ContactImportView.vue`
+
+## Test URLs (Copy/Paste into Browser)
+
+### 1. Basic Page Load
+```
+http://localhost:3000/contact-import
+```
+**Expected**: Manual JWT input page loads
+
+### 2. Single Contact Import
+```
+http://localhost:3000/contact-import?contacts=[{"did":"did:test:123","name":"Test User"}]
+```
+**Expected**: "Test User" appears in import list
+
+### 3. Multiple Contacts Import
+```
+http://localhost:3000/contact-import?contacts=[{"did":"did:test:alice","name":"Alice"},{"did":"did:test:bob","name":"Bob"}]
+```
+**Expected**: Both contacts appear in import list
+
+### 4. Malformed Data Test
+Navigate to basic page and paste this into textarea:
+```
+[{"invalid":"data","missing":"did"}]
+```
+**Expected**: Error message displays
+
+## Browser Developer Tools Validation
+
+### Console Tab
+- Check for errors during page load
+- Verify error logging works (test malformed data)
+- Look for properly formatted log messages
+
+### Application Tab
+- Navigate to: IndexedDB → TimeSafari
+- Check `contacts` table for imported contacts
+- Check `logs` table for error entries
+
+### Network Tab
+- Monitor API calls during import
+- Verify visibility setting API calls (if enabled)
+
+## Testing Checklist
+
+### Web Platform (Chrome) ✅/❌
+- [ ] Basic page loads without errors
+- [ ] Single contact import works
+- [ ] Multiple contacts import works
+- [ ] Database operations work (check IndexedDB)
+- [ ] Error handling works (malformed data)
+- [ ] Logging works (console + database)
+- [ ] Visibility setting works
+- [ ] Duplicate detection works
+
+### Expected Database Operations
+- **Insert**: New contacts added to contacts table
+- **Update**: Existing contacts updated if imported again
+- **Logging**: Errors recorded in logs table
+- **Persistence**: Data survives page refresh
+
+### Success Criteria
+- ✅ No console errors during normal operation
+- ✅ Contacts successfully imported and visible in contacts list
+- ✅ Error scenarios handled gracefully
+- ✅ Database operations work correctly
+- ✅ Logging functions as expected
+
+## Notes
+- Test both with and without existing contacts
+- Verify redirect to contacts page after import
+- Check success/error notifications display
+- Validate contact data structure in database
