Refactor the `CategoryRow` component in `netflix-grid.tsx` to improve the carousel scrolling logic. The changes include implementing instant jumps to the beginning or end of the carousel when reaching the boundaries during scrolling, and simplifying the click handlers for navigation buttons and touch areas to directly call the `scroll` function. This addresses the issue where scrolling functionality was not working correctly.
