+ * F006 用户表单弹窗 (新建/修改 共用) - W17.4.4 优化
  *
  * 后端:
  *   - 新建: POST /user/user/save  (UserDTO body)
  *   - 详情: GET  /user/user/getUserInfo?id=...
  *   - 修改: POST /user/user/update (UserFeignDTO body, 字段子集)
  *
- * 字段 (沿用老 /views/api/user.vue + UserDTO.java):
- *   nickName 昵称 (必填)
- *   mobile   手机号 (必填, 11 位)
- *   password 密码 (新建必填, 修改可选-留空表示不修改)
- *   header   头像 URL (选填, 暂不实现上传, 直接 URL 输入)
- *   sex      性别 0男1女 (选填)
- *   isEnterprise 是否企业认证 0否1是 (选填)
- *   enabled  禁用标识 0正常1禁用 (选填)
- *   remark   备注 (选填)

+ *   enterpriseId    关联企业 (单选, 取 tb_user.enterpriseId; 真多对多需后端加 user_enterprise_bind 表, 当前未做)
+ *   remark          备注 (选填)
+ *
+ * 已去掉:
+ *   - header (头像 URL): 改用默认头像, 此处无意义
+ *   - isEnterprise (是否企业认证): 由企业认证流程自动带过来, 不允许手工改
