Subject: [PATCH] feat(FSPagerViewCell): Add customizable shadow properties

- Add shadow customization properties (color, radius, opacity, offset)
- Implement updateShadow() method to apply shadow settings
- Refactor commonInit() to use the new shadow update method
- Keep backward compatibility with default values
