-- ============================================================
-- 临时权限修复：学籍异动「新增」权限（退学/休学/复学/毕业提交接口）
-- 背景：
--   前端退学按钮权限：studentMsg:status:tuixue
--   后端提交接口校验：studentMsg:studentStatusChange:add
--   系统菜单中原先缺少 add 权限码，导致有按钮但提交报 403
-- 适用：
--   朱茏老师（user_id=223，角色含 3003-学生信息管理）及同类角色
-- 执行后：
--   相关用户需重新登录，使权限缓存生效
-- ============================================================
