Create an infinite scrolling carousel for video categories

Browse Source 
Implement infinite scrolling logic in the `CategoryRow` component of the Netflix grid. This change modifies the scroll behavior to loop back to the beginning when reaching the end, and vice-versa, creating a continuous carousel effect. The navigation buttons are now always visible to facilitate this continuous scrolling. The CSS classes for the navigation buttons have also been updated to ensure their visibility and hover effects work correctly with the new infinite scroll functionality.
