修复 AecDbXSlab 的 L1-L9 内存泄漏
- L1 GetOffsetCurve 失败分支补 FreeBuffer，不再整批泄漏 offset 曲线 - L2 CreatePipeRegion 的 booleanOper 操作数未释放，成功/失败路径均补齐 - L3 IsPointInSide 折线分支返回前未删 GetBasinShapeCurve 新建的曲线 - L4 Draw2d 圆板分支与无 KEY_ORGPT 分支中未进缓存的 pShape 泄漏 - L5 SetRegionSlab(LPCTSTR) 的 explode 碎片未释放 - L6 SetEllipseBasin 的 offset 曲线与多余截面 region 未释放 - L7 PeelBasinWall 的 explode 碎片未释放（SetBaseCurve 内部 clone） - L8 SetProperties eXDB 分支的 pXYPoly 未释放 - L9 DrawHatch 未被 ConvertBoundCurve 接管的克隆、非 polyline 的 pCurve 泄漏
