feat: 与我相关点击打开侧边详情 + 开发/测试转交功能

一、工作台交互改为侧边栏详情（点击卡片打开）：
- 调研/产品/UI：新建 PlanDetailDrawer
  - 子任务勾选、进度条、上传成果（链接/文件）
  - 开始/提交完成操作、转交功能
- 开发任务：复用 DevTaskDetailDrawer
  - 状态流转、阻塞管理、前置任务等完整功能
- 测试用例：复用 TestCaseDetailDrawer
  - 测试步骤、预期结果、关联Bug、提Bug
- Bug：复用 BugDetailDrawer
  - 描述、截图、操作日志、状态转换

二、开发任务增加转交功能：
- DevTaskDetailDrawer 顶部增加转交按钮
- 从 members 列表选择新负责人
- 更新 assigneeId

三、测试用例增加转交功能：
- TestCaseDetailDrawer 顶部增加转交按钮
- 人员离职等场景可转交

四、版本详情同步：
- 所有 Drawer 改动同时生效于版本详情页
  （因为复用同一组件）
