feat(studio-3d): 历史回放里的三维面板 —— 由「重算」通道喂它,并标注来源

- What: `VIEW_SHOWS_3D` 加入 `replay`;`app_window` 新增 `_shows_3d()`(可见性与布局共用一个判据)
  与 `_splitter_sizes_for()`(预设表里的 3D 槽是"二维布局"的描述,面板打开时从最宽的面板借
  `DEFAULT_3D_PANE_WIDTH=340`);`ThreeDPanel` 新增第三个来源标签(实时采集 / 回放:录像不含三维场 /
  重算通道:由录像重算,非记录值)与 `set_source_kind()`;`ThreeDCoordinator.show_rest()` 把参考模型
  放回屏幕并停止主张测量值(重算停止时调用,否则最后一帧会留在屏幕上);`Mesh3dPanel` 转发这两者,
  并新增"加载中"状态的修正:切换传感器再切回来时若该包已加载,直接显示已就绪的画面而不是一条永远
  不会被替换的"正在加载"。
- Why: 录像里没有三维场(raw_*.mp4 是原始相机图像,`depth.stored=false`,CSV 只有力值),所以纯回放只能
  显示参考模型;但「从视频重算力值」本来就把同一个运行路径指向录像的原始视频,而采集线程上的三维 sink
  早已注册——因此重算一开始面板就会收到真实的形变帧。这两件事必须由界面区分:一个是"没有测量",
  一个是"当前算法对这段录像会说什么",把后者当成记录值展示就是另一种 `display_illustrative`。
- Verification: apps/studio 全量通过(test_scene3d_view.py 32 项,含"回放里面板可见且标注正确""重算时
  标注切换""停止重算后清回参考模型""实时视图标为实时";test_scene3d_coordinator.py 15 项,含 show_rest
  与"停止时在飞的帧不会随后被显示");ui_check 570 项 0 失败(新增"已安装包必须被加载并标注来源");
  locale_check 0 缺失;仓库内工程包经 validate_scene 全部 ok。
- Not in this change: 逐帧保存展开场/深度(记录格式变更,设计文档明确否掉);重算通道本身(已存在,本次
  只是把它的帧接到面板上);示意位移(仍需 SDK lift + 已确认尺度)。
