"""开通商品来源：不再依赖已下线的旧活动任务接口（2026-10-15 真机实测）。

真机现状（账号 hy_297832664，HTTP cdnws 通道）：
- ``webActUI.getActTaskDetail(act_id=25135)`` → 601「活动已下线」
- ``shopMiddleUI.getGoodsInfoV5`` 对 hy-8328015 / hy-8327356 / hy-5879340 均 code=200

因此刷新开通商品改为「内置商品候选 + getGoodsInfoV5 详情」，活动任务详情只做可选
补充：它失败只记 warning，不再让整次刷新失败。
