refactor: move filter bar to GameList and fix button styling

- Moved filter button bar from App.jsx to GameList.jsx for better separation of concerns.
- Updated GameList to accept filter/setFilter props and render the filter bar internally.
- Moved .new-game-button styles to global CSS for consistent styling.
- Ensured filter button styles remain in GameList.module.css.
- Improves modularity and UI consistency.
