fix(core): 商品详情页三视图改走 image_edit 参考真实主图 + 该商品 AI 素材归属

- 商品详情页「AI 生成三视图」原走独立生图老链路(纯文生图),只凭商品名脑补,
  出来通用图不像真品。改:前端传 reference_product;后端 run_standalone_image_task
  据此取商品主图走 image_edit(复用 build_product_triview_prompt_refs 锁包装),
  取不到主图优雅回落文生图。图片创作页(自由创作)不带标记,不受影响。
- 商品详情页素材区改为只显示「该商品」AI 素材(asset.product 归属)而非全团队。
- 首登水合带重试,失败不再静默(否则页面卡在全 0,要刷新才好)。
