[Uyoxy]

This PR introduces the GameCreationPage component, which implements our new game creation flow. The key changes include:

• A "CREATE GAME" card and a QR code container that share identical dimensions using shared Tailwind CSS classes.
• Dynamic generation of a game code and corresponding QR code URL using React hooks.
• Integration of a Connect Wallet button, positioned in the top-right corner.
• Responsive styling that adapts to various screen sizes, ensuring a consistent user experience.

These updates help create a cohesive and interactive interface for game creation while preparing the app for further enhancements.
