Spider Update - New Visual Features and Confirmation Dialog

The Spider game has been updated with new visual features to enhance the gameplay experience. Visual Foundation Piles have been added at the top right, starting as empty slots that fill with a King as you complete sequences. The stock pile visualization has been improved to display overlapping card backs representing the remaining deals, with a tight overlap to conserve space. Additionally, a confirmation dialog has been added for the 'Restart' action to prevent accidental loss of progress when clicking that button.
