Implement pagination on game list page

[DanielOyieke1]

Description

Add pagination to the game list page to improve performance and user experience when browsing large numbers of games. Currently, all games load at once, which can impact page load times and make navigation difficult as the catalog grows.

Why This Matters

As the Tailspin Toys game catalog expands, loading all games on a single page will negatively impact performance, user experience, and server load. Pagination ensures the platform remains responsive and user-friendly at scale.
