Refactor CSS for improved layout and responsiveness

- Adjusted board.css to prevent overflow and ensure squares maintain proper dimensions.
- Enhanced pieces.css with optimizations for animations and overflow handling.
- Updated style.css to use viewport height for board size, added overflow properties, and ensured responsive design for mobile.
- Maintained aspect ratio for chess board and refined mobile adjustments for better user experience.
