同一个剥前缀函数在 submission 和 flowchart 的管理端各有一份逐字相同的
拷贝，conf 里还有一份内联写法，合并到 utils/shortcuts.strip_class_prefix。
改名是因为原名 get_real_name 和 UserProfile.real_name 字段、以及三个
serializer 里的同名方法都容易混。
行为上修了两处：
- 剥前缀改用 removeprefix，不再按长度硬切。班级号对不上时原样返回，
旧写法会从中间截出乱码（ks999王五 配 class_name=251 会切成「王五」）
- get_class_name 的正则从 \d+ 收紧到 \d{3,4}，与前端
ButtonWithSearch 的 /^ks\d{3,4}/ 对齐。旧的贪婪匹配在姓名部分是纯
数字时会吃掉整串（ks251001 返回 251001 而不是 251）。顺带 re.search
换成 re.match，外层的 startswith 判断并进正则
正常数据（ks251张三、ks2510李四）新旧结果一致，已逐例对拍。
