test: add active identity migration end-to-end testing

- Add comprehensive migration test suite for identity switching
- Include smoke tests for basic page loading and navigation
- Test migration persistence, error handling, and data preservation
- Validate Active Identity façade functionality

Ensures the migration system works correctly across
all phases and maintains data integrity.
