Fix: Pygame Powered section issue

[Hammad-hab]

This pull request fixes the repeated-image bug in the “Pygame Powered” section of the home page.
On initial load, multiple cards display the same image. The root cause was the use of data-info attributes to store application state in the DOM. In Next.js this pattern is unreliable due to SSR/CSR transitions and should not be used for state management.

What was changed

• Removed reliance on data-* attributes for storing state.
• Added a unique event-handler generator (changeBackgroundForSpecificID) so each card has its own stable mouse-enter handler.
• Eliminated the conditional fallback logic for currentGameId, since state is now predictable.
• Refactored powered.tsx into a modern function component using React hooks (useState, useCallback).

Fixes #40
