feat(player-controller): 实现v0.1角色控制系统

- 移除跳跃逻辑：删除JumpAction、DoJumpStart/End
- 调整CMC参数：MaxWalkSpeed=450, Acceleration=2250, Brake=1500, RotationRate=720
- 调整SpringArm：TargetArmLength=350, SocketOffset.Z=80, CameraLag=6, ProbeSize=12
- 添加Pitch限幅：ViewPitchMin=-30, ViewPitchMax=45, 初始俯角-15°
- 新增交互状态：bIsInteracting + SetInteracting/IsInteracting/IsRunning
- 新增交互IA：InteractAction/CancelAction/SwitchInteractAction（占位回调）
- DoMove添加交互中忽略移动输入检查

Task: P-011
