fix: 修复 Telegram 401 错误并新增 Windows setup.bat

- fix(Config.html): telegram channel 配置字段 botToken → token，
  修复接入 Telegram 时所有请求返回 401 Unauthorized 的问题
  (影响 portable / usb-release / u-claw-app 三个版本)
- feat(portable): 新增 setup.bat，Windows 用户可一键下载
  Node.js v22 + 安装 OpenClaw + 安装中文技能包，
  对应 setup.sh 的 Windows 版本（解决 issue #10 #17）
