nxxy335 6772aeae11 feat: 抽取页分组均衡5:5 / 重置清累计 / 历史记录 / 排除管理 / 登陆账号字段 / side等高 
随机抽取页：
- 分组均衡抽取：有组别(≥2个)时默认按名额均分到组(12/8抽10→5/5)，
  其次按班级均分，否则整池随机；可勾选关闭
- 名额均分算法 allocQuotas：floor 均分 + 余数小组优先补齐 +
  超容量退回 + 差额给剩余容量大者
- 重置结果：同时清零累计已抽取数（历史记录仍保留）
- 历史记录：每批次入 localStorage ny_draw_log（上限50），
  重置不清，支持查看详情/恢复结果/删除/清空
- 抽取排除：排除管理弹窗（搜索/清空），结果行可"移出并加入排除"
- 白名单列表下载：登陆账号优先，缺失回退学号

名单登陆账号：
- 模板解析识别"登陆/登录账号/账号/手机号"列，手机号去 .0 尾巴
- Db ny_roster 增 login 列 + 旧表自动升级(三方言)
- roster_save 透传 login；draw_export 使用 login
- 登陆账号仅用于白名单列表下载，其余界面不展示

布局：side 模式下成绩明细/缺考名单 panel 改 flex 撑满，
.table-scroll 取消 320px 限高，两侧等高不再留白

测试：tools/test-draw-alloc.js 18/18 通过（含 1000 组随机 fuzz）

nxxy335 ba0e64ed51 feat: 导出按班级/组别筛选 + 随机抽取页 + 零依赖 XLSX 导出 
导出跟随分类筛选
- api.php export / export_absent 新增 cls、grp 参数，按当前筛选过滤 rows
- 缺考口径与页面完全一致：筛选后名单 − 筛选后已提交（按学号匹配）
- 导出文件名附带班级 / 组别（如 成绩明细_高一数学月考_高一(1)班_A组_时间戳.csv）
- app.js 两个导出按钮追加 cls/grp 参数并提示导出范围

随机抽取页 draw.php
- 来源：学号名单 / 某试卷已提交人员；支持班级、组别筛选与抽取人数设置
- 「排除已抽中」累计去重，抽取结果存入 localStorage，刷新后仍可下载
- 抽取动画（滚动定格），结果表格含序号 / 学号 / 姓名 / 班级 / 组别
- 下载「白名单导入模板.xlsx」「白名单列表.xlsx」：两列 姓名 / 登陆账号

XLSX 导出能力
- 新增 lib/XlsxWriter.php：零依赖生成 xlsx，有 zip 扩展走 ZipArchive，
  无则回退手写 ZIP(stored)；单元格按共享字符串 + 文本格式(numFmtId=49)
  写入，长学号不会变科学计数法
- 新增 api.php action=draw_export，输出与「白名单列表.xlsx」模板一致的结构

其他
- index.php 顶栏新增「随机抽取」入口；支持 index.php#roster 直接打开名单管理
- tools/test-xlsxwriter.php 自测：18 项全通过（含无 ZipArchive 的手写打包路径）
