nxxy335 a3be81b261 fix(security): 修复上传名单文件可被 URL 直连访问(nginx 下可 getshell)
严重漏洞:roster_import 使用 $_FILES 的原始扩展名拼 roster_YYYYMMDD_HHMMSS.<ext>
落在 Web 根目录内的 data/uploads/,既无扩展名白名单(可上传 .php),文件名又
可按秒枚举;而 bootstrap 只写了 data/.htaccess,nginx 不读 .htaccess,
生产环境(nginx + PHP-FPM)下可直接远程代码执行。

修复(api.php roster_import 四层防护):
- 扩展名白名单:仅 xlsx / xlsm / csv / txt
- 随机文件名:bin2hex(random_bytes(16)),杜绝枚举
- 解析完成后 @unlink 立即删除,Web 目录下不留存任何上传文件
- 20MB 大小限制 + UPLOAD_ERR 检查

加固(bootstrap.php):data 及 cache/uploads/snapshots 每个目录都写
.htaccess(Deny from all)+ index.html 占位;README 与文档补充 nginx
location ^~ /data/ { deny all; return 404; } 规则。

测试:新增 e2e tools/test-upload-guard.js(11 断言,覆盖 .php/.phtml 被拒、
无残留、合法 csv 导入成功且即删、无可枚举文件名),并入 tests/run-all.sh。
全套 90 项通过。

docs: 新增 VitePress 文档站(18 页)
- 使用指南 12 页:简介/部署/快速上手/系统设置/名单管理/统计口径/试卷设置/
  快照趋势异常/导出打印/数据看板/随机抽取/常见问题
- 安全 2 页:安全总览(含本次漏洞复盘)与部署加固清单(P0-P2)
- 开发 4 页:架构与目录/接口一览/SQLite 存储/测试
- 配图迁移至 docs/public/images/;.gitignore 忽略文档构建产物
