- 迁移 000099：tb_package_usage 新增 package_name 列，回填历史数据 - PackageUsage model 添加 PackageName 字段（与 DataResetCycle 保持一致的快照设计） - 4 处 PackageUsage 创建点补充 PackageName 快照（order/service.go + auto_purchase.go） - EnterpriseCard ListCards：carrier_name 直接取 card.CarrierName，package_name 通过 DISTINCT ON 批量查当前生效主套餐，单次查询覆盖整页，无 N+1
