refactor(validators): Add support for injection components

Injection components (like theme-settings) are special components that:
- Don't render visual HTML (inject code into wp_head/wp_footer)
- Don't need visibility group (always enabled)
- Don't need CSSGeneratorInterface (output user-provided CSS)
- Don't need getVisibilityClasses (not responsive visual elements)

- Update Phase01Validator to skip visibility check for injection components
- Update Phase03Validator to skip CSS/visibility validations for injection components
