feat(admin): 报名导入新增「从已有名单勾选报名」

原来只能上传 CSV/XLSX。现在同一个 tab 上方多一个选择器：选小项 → 组别 → 单位，
从该单位已有运动员里勾人，一键加入报名。

- 个人项目：勾 N 人 → N 条报名（一人一行）
- 团体/对抗项目：勾 N 人 → 1 条报名，姓名拼进 member_names（再次提交即更新队员名单）
- 已报名的人/单位会标「已报名」并禁止重复勾选
- 复用服务端唯一报名入口 POST /entries/import：勾选结果转成同格式 CSV 提交，
  字段校验、按 (组别,单位,运动员) upsert、行级报错回显与表格导入完全一致
- 纯函数 entrySelection.ts（表头唯一来源 + RFC 4180 转义）+ 4 个单测；
  表头定义从 ImportSection/mockBaseData 收敛到一处
- 号码布/种子仍走表格导入，界面与文档都写明

自检：vue-tsc + pnpm build 通过，前端 node --test 30/30。

 ### 10.7 报名导入
 
+报名有两种方式，都在本页完成：**从已有名单勾选**适合零散补报，**表格导入**适合批量录入。
+
+**从已有名单勾选**
+
+1. 依次选择小项、组别、单位；
+2. 在运动员列表里按姓名 / 工号搜索并勾选：
+   - 个人项目：勾选的人各生成一条报名；已报名的运动员显示「已报名」且不可重复勾选；
+   - 团体 / 对抗项目：勾选的人合成一条报名，队员名单按列表顺序写入；该单位已报名时再次提交会更新队员名单；
+3. 点「加入报名」，结果同样显示**新增 / 更新 / 跳过**数量。
+
+**表格导入**
+
 1. 点「下载 CSV 模板」获取表头样例；
 2. 表头必须包含：`event_code`、`category`、`team_code`、`athlete_name`、`bib`、`seed`、`status`、`member_names`（大小写不敏感）；
 3. 把 `.csv` 或 `.xlsx` 拖入虚线框，或点击选择文件（单个文件不超过 16MB；xlsx 只解析第一个工作表）；
 4. 点「开始导入」，页面显示**新增 / 更新 / 跳过**数量；匹配不到的行会跳过并回显行号，修正后可重新上传。
 
+号码布、种子等字段无法在勾选界面填写，仍需通过表格导入。
