fix(listing): 外部上传按后台实时配置归类皮肤与折算消耗品，并补齐新增消耗品字段

- 皮肤归类：删除代码内硬编码的 externalSkinCatalog 快照，改为读取 listing.publish_options。
  修复运营在后台新增皮肤后，上传的商品被归入 other 的问题（详情页显示“其他皮肤”、
  按刀皮/金皮/红皮/武器皮分组筛选搜不到）
- 消耗品折算：externalResources 改为按 publish_options.quantity_items 生成条目与单价，
  修复 AWM 子弹按 0.6 元/发旧价折算等价格漂移（线上已调为 0.7 元/发）
- 上传契约：ExternalUploadInventory 新增 level6Ammo/barrettAmmo/gridCard9/redPacket45/
  coffeeBean/bulletPart 六个字段，字段名与消耗品 key 对齐；后续后台再新增消耗品，
  按同样 key 登记即可被上传链路识别
- 数量为 0 的消耗品不再写入资源清单，与网站自身发布流程（filter quantity > 0）保持一致
- 客服调整外部商品同样改用实时单价；Service 增加 externalPublishOptions 统一读配置并带默认值
- 验证：新增回归测试 TestExternalAccountToCreateRequestFollowsPublishOptions；
  并以线上 mobile-home-config 的真实配置 + 上传工具产出的 JSON 做跨仓库联调，
  确认“重塑→近战皮肤、骇爪-骇客少女→干员金皮”，9 项消耗品全部按线上单价生成
