fix a hint bug

Fixed an issue where completing a number failed to make it semi-transparent.

Added a button to toggle the fireworks on or off. Hold Ctrl while clicking the button to toggle the fireworks sound on or off. Manually disabled lines are now marked with a small × to distinguish them from automatically disabled lines.

Show fireworks when you finish a level.

Fix the issue where certain modes in the repair and hint functions cannot be recognized, and resolve the problem where no error is displayed when a single point has three connecting lines.

An update has been made, and now you can disable play the piano note. Simply hold down the Ctrl key and click the sound effect (speaker) button in the settings to toggle this setting. Additionally, the markers without connecting lines have been changed to shorter dashed lines.
