Update money_memory_game.py

[TacticalReader]

Changes in money_memory_game.py:

• Completely refactored the script using an OOP approach with a MemoryGame class (better code organization and extensibility).
• Enhanced the GUI:
  • Bigger, styled buttons for a more engaging look.
  • Added score, attempts, and accuracy status bar.
  • Added a dedicated restart button.
  • Provided visual and sound feedback for game completion.
• Improved game logic:
  • Prevents rapid or overlapping clicks with a lock mechanism.
  • More robust handling of matching, mismatching, and resetting UI states.
  • Tracks and displays statistics (matches, attempts, accuracy).
• Improved code readability and maintainability by removing old procedural logic and redundant comments.
• Compatible with Windows sound feedback (auto-pass on non-supported systems).

Summary:
Upgraded the memory game with a modern class-based design, a better interface, improved UX, more features (restart, sound, status), and robust logic. All gameplay elements are now handled within an organized, extensible class.
