feat: 图像增强/变换算子标记高级参数+默认值优化

高级参数标记：Contrast(Contrast,Brightness,UseCLAHE,ClipLimit)、
Gamma(Gain)、Sharpen(Method,KernelSize)、Emboss(BlendRatio,GrayOffset)、
HistogramEq(Method,TileSize)、HDR(Method,Saturation,SigmaSpace,SigmaColor,Bias)、
Hierarchical(BaseGain,ClipLimit)、Retinex(Method,Sigma1/2/3,Offset)、
Rotate(ExpandCanvas,BackgroundValue,Interpolation)

默认值优化(适配平面CT DR图像)：
- Sharpen: Laplacian→UnsharpMask(对噪声更温和)
- HistogramEq: Global→CLAHE(局部对比度更优)
- Contrast: AutoContrast默认开启
