界面改用「精密仪器工作台」布局：顶栏压缩、视图切布局、标定与回放面板不再裁切

- What: 品牌条 40→28px 并加 实时监测/历史回放/标定 导航；导航改为切换主界面三套布局（实时=2D图像+曲线、回放=自动全程浏览、标定=标定面板 880px+曲线，2D 图像整体缩小）；传感器选择（传感器 / 传感器配置 两个带 tooltip 的下拉 + 产品徽标）移到状态轨最左侧，记录模式移入设置区；新增 RecordStatusChip（记录中时长、丢帧、写入异常）与「同一时刻只有一个实心按钮」（新增 dangerOutline 描边危险样式）；三轴读数移到曲线上方（16pt 等宽）、只保留最下方时间轴、网格淡化、全程浏览条可拖动；三轴配色统一为蓝/橙/绿并把语义色对比度审计扩展到 toolbar_bg；箭头页脚显示放大倍率与有效区域，深度模式才显示色条与范围；左侧面板改名「2D 图像」且固定显示图像宽高比；标定面板加纵向滚动区、九按钮分两行、六列表头 ResizeToContents；PlaybackDialog 补上从未调用的 retranslate；main() 在事件循环结束后 flush 日志并 os._exit，避免设备 SDK 原生线程把进程挂在解释器收尾。
- Why: 评审提出的 7 点：顶部占高与装饰过多、记录状态不突出、配置切换看不懂且藏得太深、切视图应换主界面布局、标定与回放面板文字被裁、关窗后命令行不退出、2D 图像无固定宽高比且名字不符。
- Verification: ui_check.py（430 项，新增 top area / instrument panels / clean shutdown 段，含中英×1280/1440 的轨不挤压检查）、test_ui_smoke.py（57 项，新增视图切换、标定不裁切、2D 宽高比、回放按钮文字、传感器选择器等用例）、drive_shared.py（146 项）、locale_studio.py（261 键齐全、zh==en、prefs 对齐）、reproduce.py、ui_snapshot.py 四张复核图。
- Not in this change: 录制文件格式、CSV/MP4 写入路径与记录通道数据流不变；三维面板仍是占位符；回放对话框（含离线深度重算）本身只修了按钮文字。
