feat(web,android): 看板拖拽、详情侧栏编辑、快速录入与安卓任务列表

Web:
- 看板四列可拖拽，非法流转当场说明原因；勾选后可批量移动
- 详情侧栏全部可编辑（标题/优先级/截止/标签/备注/评论），409 自动刷新
- 快速录入 #标签 !优先级；键盘流 j/k、Enter、e、Esc
- Playwright 真浏览器 e2e 7 项断言全绿（web/e2e/smoke.mjs）
- 1000 条任务实测首屏 P50 38-55ms

Android（未编译验证：本机无 JDK/Gradle）:
- 任务列表/详情/勾选完成/快速新建，冲突时提示并刷新
- 修：User/Member 字段名与后端 nickmame/phone 对齐，原先必然反序列化失败
