feat(douyu): 和平小店绑定功能(生成绑定二维码/查询绑定信息)

- activity_client: xpd_bind_qr(roleParam 签发 livelink 绑定链接, 微信扫码进小程序绑定)
  + xpd_bind_info(bindInfo 查询绑定状态/角色/平台), gameRole 非 dict 边界防护
- runner/service: 注册 get_xpd_bind_qr / query_xpd_bind_info 任务, 回写
  xpd_game_name / xpd_bind_status
- router: get_xpd_bind_qr 的 url 加入列表接口保留白名单(二维码展示)
- 前端: 和平小店面板新增两个按钮, 二维码列支持 get_xpd_bind_qr 展示/放大
