feat: 完善/优化/新增大批次 + 安全加固 + 性能优化
- 修复再次提交不置顶(排序键改用 last_submit_ts) - 后端结果缓存 + 并发锁(DataCache / ny_build_data / Roster 指纹失效) - 导出 xlsx 多表:按最新成绩 / 按班级分表 / 可选列 - 名单管理:新增改弹窗、删除多选+二次确认、登陆账号列 - 安全:CSRF token + 登录失败限流(5次锁10分钟) - 未匹配答卷一键加入名单(unmatched_map) - 缺考名单增强:复制学号/姓名、按班统计、打印 - 成绩快照 + 跨卷趋势(Snapshot) - 异常检测线索(短时长高分/高频重考/雷同成绩) - 前端性能:虚拟滚动、搜索防抖、后台暂停、失败退避 - 测试沉淀:test-new-features.php + run-all.sh
