Enhance test infrastructure with standardized patterns and factories

- Add comprehensive contact factory with 3 complexity levels (simple, standard, complex)
- Create centralized test utilities with performance, accessibility, and error helpers
- Standardize test data patterns across all component tests
- Add test data factories for RegistrationNotice, ProjectIcon, and ContactBulkActions
- Improve test structure consistency with better beforeEach patterns
- All 149 tests passing with enhanced error handling and performance testing
- Establish foundation for scalable test development with reusable utilities
