feat: MCP Unity 场景优化 — 完整交互体系搭建

- 删除重复 Ground
- 创建 [Managers] 空物体，挂载 GameManager + StepManager + ExperimentFlowCoordinator + AudioManager
- Main Camera 挂载 InteractionSystem
- 伤者 InjectedPerson 下创建 5 个交互子物体 (InjuryVisual/Swelling/Pain/VitalSigns/Neuro)
- 创建绑带位置、踝关节、衬垫、夹板位置等空物体
- 道具摆放到位：伤者(2,0.05,5) 施救者(3,0,5) 鞋(2.7,0.15,5.5) 绷带/夹板/急救箱在旁
- InjuryLeg Tag 修正，Ground Tag 修正
- 全部新脚本同步导入 (ExperimentTypes/StepData/ExperimentConfig/StepManager/GameManager/ExperimentFlowCoordinator/InteractionSystem/DraggableObject/HighlightEffect/UIManager/ExamPopup/ScoreDisplay/VideoController/AudioManager/CharacterAnimController/StepAnimationHandler)
- 旧脚本 (ExperimentController/ConfigLoader/AnimationController/HUDController/VideoPlayerController/PopupSystem/ModeSelectionUI) 全部兼容修复或 stub
- 编译通过，0 错误
- Canvas 挂载 UIManager
