-- 真退款链路：退款单状态与金额落库（幂等，可重复执行）
|
||
--
|
||
-- 本迁移与 internal/logic/migrate.go 的 migrateColumns() 内容一致：
|
||
-- 服务端启动时 Migrate() 会自动加列（项目约定：升级只需重启服务）。
|
||
-- 本文件供运维在无法重启 / 需要手工核对时使用。
|
||
--
|
||
-- 新增列：
|
||
-- member_orders.refund_no 商户退款单号（唯一；失败重发换新号）
|
||
-- member_orders.refund_status 退款状态：0未退款 1退款中 2退款成功 3退款失败
|
||
-- member_orders.refund_amount 退款金额（分，全额退款 = paid_price_cents）
|
||
-- member_orders.refund_reason 退款原因（后台登记，iOS/手工退款必填）
|
||
-- member_orders.refund_finished_at 退款确认完成时间（回调 / 查单轮询 / 手工登记）
