fix(V0.2): 三轮反馈 5 项 —— 回滚键盘方案 / 列表卡片拖动 / 看板防误触 / 横滑整屏 / 详情页恢复

1. 回滚键盘遮挡统一方案 (真机测试不通过, 需求搁置): 恢复 TaskDetail/
   UserPicker/CopyTaskPopup/ProjectManage 与 useKeyboardInset 到 9fea1a5^,
   删除 useKeyboardInsetWatcher / .kb-safe / interactive-widget=resizes-content
2. 任务详情页样式随 1 一并恢复提交前状态 (含底部拷贝/删除按钮)
3. 列表视图换列改为卡片拖动: 新 useRowDrag (长按 400ms 行抬起, 左右
   80px/列步进, 行尾徽标显示目标列, 松手落列), 移除长按 ActionSheet
   —— 旧长按与复选框/行点击互相误触, 抬手合成 click 落在控件上触发状态切换
4. 看板拖动防误触: 任务区禁长按文字选择与系统菜单 (输入框除外);
   pointercancel 只放弃不提交; 拖动结束 350ms 内抑制 click 误开详情;
   状态点/⋯/子任务行 pointerdown 不冒泡, 不发起拖动
5. 看板横滑扩展到整屏: .page-transition 补 height:100% 打通
   app-main → page-with-navbar 百分比链, board-wrap 撑满剩余高度
