重构 Autocal 采集页：单一队列与控制器驱动的主按钮

选点、对准、加载与录像分散在两个面板，状态靠隐藏相位判断。现改由不依赖 Qt 的采集控制器驱动，并加入录像选项、汇总平铺副本、保持到时自动结束、会话结束回到空闲，以及无设备时的模拟采集。已运行 Autocal 非 Qt 测试并通过范围内门禁；界面测试待 Windows 复核，未做实机验收。

 **Existing code:** the motion layer has the guards and the poller; the step

+**As built today** (manual, through the capture page): the operator keeps one
+queue of points — a single point is a queue with one row. `Ready` must be all
+green before the first point. The page shows one primary button whose label is
+the next step (align → start → at the target → hold finished → confirm liftoff →
+finish) and states the reason whenever it is disabled. Alignment only requests a
+guarded pose move, and a capture may not start until that move has completed, so
+a repeat can never be recorded on a pose nobody confirmed. Remeasure, skip and

+Changing the mounting offset, the tool XY or the travel limits re-solves every

+exported operation table comes from the same queue (queue → 导出测点操作表…), so
+the table and the run cannot describe different points.
