修复：统一比价记录状态枚举口径 (#209)

## 变更说明 - below_minimum 归入成功，保留原始业务结局 - store_closed/store_not_found/items_not_found/no_delivery/unsupported 归入失败 - running 保持进行中生命周期状态 - 历史细分状态迁移为三态终态，迁移可逆 - 后台成功/失败筛选及汇总兼容迁移前历史值 ## 验证 - 相关回归：48 passed - Ruff：通过 - Alembic：单一 head --------- Co-authored-by: guke <guke@wonderable.ai> Co-authored-by: linkeyu <798648091@qq.com> Co-authored-by: unknown <798648091@qq.com> Reviewed-on: #209 Co-authored-by: linkeyu <linkeyu@wonderable.ai> Co-committed-by: linkeyu <linkeyu@wonderable.ai>
