feat(记账): 比价省钱记账后端 M1(savings_record 唯一真相表 + /order/report + demo 兜底) (#10)

从最新 origin/main 重拉的干净分支,只含本人记账改动,不含 marco 的归因订单(order_record)——后者是另一条未合并分支 feat/user-order-records 的功能,此前被误用 git add -A 和记账混进了 feat/savings-accounting-m1。本分支不带它:savings_record 升级为唯一真相表(新增原价/比价价/支付渠道/源平台/幂等键等列,迁移 savings_report_fields 直接挂 f01db5d77dac、不经 order_record_table);/order/report 改写 savings_record(source='compare'),省额=源平台原价−实付;展示 /api/v1/savings/* 真实优先 demo 兜底。无 order_record 的 model/repo/迁移/路由。alembic 单一 head + pytest 54 passed。 Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> --------- Co-authored-by: xianze <ze@192.168.0.138> Reviewed-on: #10 Co-authored-by: zhangxianze <zhangxianze@wonderable.ai> Co-committed-by: zhangxianze <zhangxianze@wonderable.ai>
