refactor: 出库时间更名为首次购买套餐时间，换货新资产不再按换货完成时间记录

- 字段 outbound_at → first_purchase_at，记录表 tb_asset_outbound_record → tb_asset_first_purchase_record，接口 /outbound-records → /first-purchase-records，筛选参数与导出列同步更名
- 换货后的新资产不因换货写入，在当前世代真正支付套餐订单时才记录；记录来源只保留 order / backfill，去掉换货单字段
- 迁移 000266 重命名列、表、索引与约束；同步 Spec、设计、任务与前端接口变更说明
