Enhancement – Screenshot Component Improvement

• Improved screenshot rendering quality by increasing the canvas scale from 1 to 2, resulting in sharper and higher-resolution images.

• Added explicit backgroundColor: "#ffffff" configuration to prevent unwanted background artifacts during image generation.

• Enabled useCORS: true to improve compatibility with external resources.

• Refactored and simplified the implementation by removing unused dependencies.

• Minor internal code cleanup for better maintainability and stability.

These updates improve visual fidelity, reliability, and overall performance of the screenshot generation process.
