feat(sdk): 补用户-角色/URD 职务/职务名/部门名的批量查询方法

RoleManager.GetUserRolesByUUIDs：批量取 UserRole 行；PositionManager.GetUrdPositionRowsForUrds：一次取多个 URD 的职务子表行；PositionManager.GetPositionNameMap 与 DepartmentManager.GetDepartmentNameMap：批量 UUID→名称映射（字节键，避免 UUIDObj/bytes hash 不等）。

均为列表页批量富化所需的低层原语，供子项目替代逐个 filter 与手写映射循环。
