Refactor "Similar Content" UI for modern layout and responsiveness

- Refactored `SimilarContentCard.js` to use Flexbox layout.
- Updated `css/tailwind.source.css` to remove grid layout and use standard flex utilities.
- Improved thumbnail sizing (16:9, fixed width) and responsiveness.
- Added hover effects (background color, thumbnail zoom).
- Cleaned up typography and metadata hierarchy.
