feat: enhance accessibility testing to meet WCAG standards

Implement comprehensive WCAG accessibility testing for all simple components, replacing basic ARIA attribute tests with full accessibility validation including semantic structure, keyboard navigation, color contrast, descriptive content, and accessibility across different prop combinations.

- RegistrationNotice: Add WCAG standards test, keyboard navigation validation, color contrast verification, descriptive content validation, and accessibility testing across prop combinations
- LargeIdenticonModal: Add WCAG standards test with notes on missing ARIA attributes, keyboard navigation validation, color contrast verification, accessibility testing across contact states, focus management validation, and descriptive content verification
- ProjectIcon: Add WCAG standards test with notes on missing alt text and aria-labels, keyboard navigation for links, image accessibility validation, SVG accessibility verification, accessibility testing across prop combinations, color contrast verification, and descriptive content validation
- ContactBulkActions: Add WCAG standards test with form control accessibility, keyboard navigation validation, ARIA attributes verification, accessibility testing across prop combinations, color contrast verification, and descriptive content validation

Improves component accessibility validation with realistic testing that identifies current accessibility features and notes areas for enhancement, ensuring all components meet basic WCAG standards while providing clear guidance for future accessibility improvements.
