feat(douyu): 新增和平小店查询模块(绑定角色/商品列表/点券余额)

- activity_client: getIframeUrl 签发 code/sig,道聚城 getrole.out/recommend/balance 接口
  (2026-08 起需 isCode=1 + authType=delegate + sAnchorId 才能通过 Livelink 校验)
- 迁移 0016: accounts xpd_* 字段、douyu_config 小店配置(actAlias/actId/rid)、
  douyu_xpd_goods_snapshot 商品快照表
- runner/service/router/schema 注册 query_xpd_role/refresh_xpd_goods/query_xpd_balance
  三个任务,任务结果剥离 role.raw 防 openid 泄露
- 前端: 和平小店路由/菜单/DouyuTasksPage 三态/商品下拉/配置弹窗
