修复 XEquipment 外壳/Impl 分离机制的 M1-M7 缺陷

- M1 createParamEquImpl 成功替换前释放旧 impl，消除 inplace 编辑泄漏
- M2 copyFrom2 先克隆成功再替换，避免旧 impl 泄漏或被置空
- M3 copyFrom 补基类深拷贝并兜底重建 impl，修复 clone/复制得到空壳
- M4 在 XEquipmentImplBase 注明 impl 不拥有 xdata 的所有权契约
- M5 draw3dByImp 改用临时数组，绘制失败时保留旧 3D 缓存并提示
- M6 抽出 makeTempClone()，集中 ToJson 的克隆/补数据/拷 part 流程
- M7 getUniqueName 的 %s 统一传 LPCTSTR、修正 sizeof，XL 的 %d 改 %f
