fix(test): 修复测试文件类型错误和测试数据库 schema 过期问题

- 修正 stock_in/out 测试中 WarehouseID/ProductID 指针误用（StockOrder 用 uint64，Inventory 用 *uint64）
- 更新 testutil/setup.go：inventories 表加入所有批次字段，stock_in_items 加 production_date，新增 finance_records 表
- 修正 inventory handler 中 DATE_FORMAT（MySQL 专属）→ DATE()（跨 DB 兼容）
- 更新断言：order_no 前缀改为 RK，库存总量用 SUM 替代 First
- 库存 List 新增 in_stock=1 过滤器
