feat(dept): 自定义部门成员弹窗改为穿梭框，左侧全部人员、中间箭头、右侧已有成员

- 布局对齐「分配应用用户」：左「全部人员」（本校教职工候选）+ 中间 < > 箭头 + 右「已有成员」
  （原先左侧是当前成员、右侧是候选勾选，方向与本系统其他页面相反）
- 两栏都带搜索框、全选框与计数；左栏保留服务端 keyword 检索（候选上限 200）
- 交互改为待提交模式：箭头只改本地 pending，点「保存」才先 Add 再 Remove，
  取消整体丢弃；未产生变更时保存按钮禁用，底部显示「新增 N 人 · 移出 M 人」
- 支持双击行快速移动；移出后的人员回到左侧列表，方便反悔
- 全选/半选按「当前可见行」判断，关键字筛选后不会误判
