feat: 人员分配模块前端实现

前端实现：
- userAssignment.js: API接口封装（56行，5个接口）
  - getUserAssignmentList(): 分页查询
  - getUserListByDept(): 按部门查询
  - assignUser(): 分配用户
  - batchAssignUsers(): 批量分配
  - removeUserAssignment(): 移除分配

- userAssignment.vue: 人员分配页面（408行）
  - 搜索功能：用户名、真实姓名、部门（树选择）、岗位、状态
  - 表格展示：用户信息、部门标签、岗位标签、职位、状态
  - 批量操作：多选批量分配
  - 筛选功能：仅显示未分配用户
  - 分配对话框：部门树选择、岗位下拉、职位输入
  - 移除分配：确认后移除部门/岗位关联

技术特点：
- 多条件组合搜索
- 表格多选（el-table selection）
- 部门树选择器
- 岗位下拉选择
- 状态标签展示
- 批量分配优化

模块状态：✅ 完整（前端+后端）
