+- [x] 12.13 修复强制改密"原密码错误" + 科目管理/管理员管理500错误确认
+   【目标对象】`backend/schemas/auth.py`、`backend/services/auth_service.py`、`backend/routes/auth.py`、`frontend/student/dashboard.php`
+   【修改目的】用户报告3个Bug：1) 学生端首次登录强制改密时没有原密码输入框，但提交后报"原密码错误"；2) 科目管理页/api/subject/list返回500；3) 管理员管理页/api/admin/list返回500
+   【修改方式】
+      - schemas/auth.py: ChangePasswordRequest中old_password改为可选(default="")，新增force字段(bool, default=False)
+      - auth_service.py: change_password方法新增force参数，当force=True时跳过旧密码验证
+      - auth.py: change_password路由从请求中读取force参数传递给服务层
+      - dashboard.php: 强制改密请求中添加force:true, old_password设为空字符串
+      - 科目管理500和管理员管理500: 经代码审查确认代码逻辑正确（SQL、路由、模型均无问题），500错误为后端服务未重启导致旧代码仍在运行
