feat(processing_pipelines.py): 启用 3D散点/风玫瑰/风速时序图表创建

两处修改：

1. InSituSensorStrategy.process():
   - 原代码: scatter_3d[gas]=None, windrose=None, wind_timeseries=None
   - 修复: 调用 plotting.scatter_3d()/windrose()/time_series() 创建实际图表，
     每个调用独立 try/except 保护，失败时回退至 blank_figure()

2. 模块导入:
   - 新增 import plotly.graph_objects as go
     供 Curtain/Spiral 空间策略中的 fig.add_trace(go.Scatter3d(...)) 使用
     （该代码此前存在但从未执行，因为 fig 始终为 None）

影响范围：HTML 报告中 3D 飞行轨迹图、风玫瑰图、风速时序图从空白变为正常显示
