feat: 完善/优化/新增大批次 + 安全加固 + 性能优化

Browse Source 
- 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
