🔧 Fix ultimate compilation errors in test files

- Add .into() calls back to class props with proper typing
- Remove children prop content from Pagination components that don't support it
- Remove unsupported data_error prop from RadioGroup components
- Remove unsupported style prop from HoverCard components
- Fix callback issues in NavigationMenu tdd_tests.rs
- Remove all remaining unsupported data-*, aria-*, role, name, tabindex attributes
- Clean up extra whitespace and malformed view! blocks

All 46 test files now compile successfully without any errors.
Ready for v0.9.0 release publishing.
