Add Netflix-style video browsing with categorized rows

Introduces a new `NetflixGrid` component to display videos in categorized rows, similar to Netflix. This includes styling for hidden scrollbars, adding a `className` prop to `VideoCard`, and updating the home page to conditionally render either the `VideoGrid` or the new `NetflixGrid` based on the `viewMode`.
