Refactors the `CategoryRow` component in `netflix-grid.tsx` to implement infinite scrolling for the video carousel. This includes replacing the `getVisibleVideos` function with a `useEffect` hook to handle resetting the `currentIndex` when it exceeds the total number of videos, and updating the JSX to render a duplicated array of videos with a dynamic `translateX` transform for seamless looping.
