feat(finance): 补齐自动发货与接单平台成本和对账

自动发货：价格导入支持 --effective-from，把首次基线版本回填到历史起点；41,676 个订单项全部归一并生成采购成本快照，缺失 0。\n\n接单平台：新增按工单 product_rule_id 回填商品的接口与按钮，长尾项按 provider+shop_id+sku_code+normalized_sku_name 补建 wo: 商品和 sku_code_name 渠道映射；118,053 个订单项全部归一。\n\n成本：已验收工单按 reward_amount 写 actual；未验收但已确定报酬的工单写 estimated，验收后升级。全量 95,870 actual + 21,217 estimated，actual 与 reward 0 差异。\n\n剩余 966 条取消/零报酬工单保留在成本异常队列，不自动记 0；人工块未改动。\n\n实测自动发货与接单平台未归一收入均为 0；整体未归一 79.67% 降至 57.54%，全部来自人工块。

  * - 标准商品编码固定为 `aff:<sku>`，载体 affiliate_dash；
  * - 成本版本范围 = 标准商品，金额 = 上游 cost_amount（分）；
- * - 同一商品已有相同金额的生效版本时跳过；
