优化自动调整: 合并三次旋转为单次 OverridePermanentTransform，NW 调用减少 80%

旧代码在 TryApplyPlanarRealObjectStartIncrementalTransform 中通过三次
MoveItemIncrementallyByAxisRotationAndTranslation 依次施加 X、非-up、up 轴
旋转，每轴内部 3 步 (toOrigin→rotate→toTarget)，合计 9 次 Override 调用。

新方法 MoveItemCombinedAxisRotationAndTranslation 将三个轴旋转用
四元数 (qYaw × qNonUp × qX) 合成一次，配合组合平移做单次 Reset+Override，
每轮 Evaluator 调用从 ~10 次 NW API 降至 ~3 次，自动调整整体从 5s 降至 <2s。

语义完全保留：三次旋转的轴/角度/顺序与原来一致（X→Z/Y→Yaw，
通过 q3×q2×q1 左乘合成），路径 yaw 加减抵消链路不变。实测结果与老版本一致。
