feat: CVAT 标注引擎、我的标注收件箱与 ADAS Cuboid 送标

- 统一标注引擎为 CVAT：客户端/配置/格式转换、iframe 标注页、docker-compose.cvat.yml 与 no_auth 补丁
- 移除 Label Studio 相关配置与构建脚本，清理 embedded.bak 备份与误提交的 node_modules
- 新增「我的标注」：跨 Campaign 收件箱、逐张清单、CVAT frame 跳转
- 飞书任务分配：通讯录同步选人、按量分配、分配后 DM 通知（含 my-tasks 链接）
- ADAS cuboid_7cls 数据湖接入：workflow 路径、register-batch、开标上传与标注同步
- 数据湖挂载 AS_DATA_LAKE_ROOT、datasets/adas 符号链接、reset_labeling 运维脚本
- 补充 docs/HANDOVER.md 项目交接文档
