test(sanitizer): update HtmlPurifierSanitizer tests to align with new behavior

Following the refactoring of HtmlPurifierSanitizer, the tests have been updated to:

- Add explicit allowedTags configuration in each test case
- Verify content preservation when tags are removed
- Test hierarchical structure maintenance
- Ensure attribute handling works correctly for allowed/disallowed tags
