fix: 补全遗漏的 botToken 修复（config-server + 官网教程）

code review 发现三处漏修：
- fix(config-server/public/index.html): botToken → token，
  这是实际运行的配置页面，漏改会导致用户配置后仍然 401
- fix(website/tutorial.html): 示例 JSON botToken → token
- fix(website/guide.html): 示例 JSON botToken → token
  文档示例错误会导致用户手动配置时照抄出错

全仓库现已无 botToken 残留。
