feat: Add comprehensive unit testing infrastructure with Vitest and JSDOM

Add complete testing setup for Vue components using vue-facing-decorator pattern.
Includes 94 tests across 4 simple components with comprehensive coverage.

Components tested:
- RegistrationNotice (18 tests) - Event emission and conditional rendering
- LargeIdenticonModal (18 tests) - Modal behavior and overlay interactions
- ProjectIcon (26 tests) - Icon generation and link behavior
- ContactBulkActions (30 tests) - Form controls and bulk operations

Infrastructure added:
- Vitest configuration with JSDOM environment
- Global browser API mocks (ResizeObserver, IntersectionObserver, etc.)
- Path alias resolution (@/ for src/)
- Comprehensive test setup with @vue/test-utils
- Mock component patterns for isolated testing
- Test categories: rendering, styling, props, interactions, edge cases, accessibility

Testing patterns established:
- Component mounting with prop validation
- Event emission verification
- CSS class and styling tests
- User interaction simulation
- Accessibility compliance checks
- Edge case handling
- Conditional rendering validation

All tests passing (94/94) with zero linting errors.
