feat(退款): AUG26-006 退款方式选择与原路退款

按 PRD 2.3/2.4/2.5 落地套餐退款的方式矩阵与原路渠道退款:

- 退款申请派生并冻结权威实收金额(线上取原成功支付记录,钱包/线下取订单实际收款),
  提交人不可填写或修改;按来源支付方式生成可选方式矩阵并在创建、提交、执行前重复校验。
- 审批切换为「每次提交一条不可变审批尝试记录 + 独立企业微信审批实例」,业务标识取尝试
  记录主键;终态消费按尝试记录优先、退款申请兜底双读,兼容存量无实例与已关联实例申请。
  新增活动退款部分唯一索引 (order_id) WHERE status IN (1,5,6)。
- 本地人工终审保持既有开关,补齐通过入口的 approval_instance_id IS NULL 守卫,使三个
  入口一致拒绝已关联审批实例的申请;重提按尝试模式重写(仅已拒绝/已退回/原路失败且无异常)。
- 权益时点:企微通过事务写退款终态、按方式确定的订单态、钱包回款、员工账单冲销与可靠
  失效事实;套餐失效/接续/停机仍由既有可靠机制最终一致执行,不把外部调用放入资金事务。
  订单支付状态按方式置位:凭证退款与退回原钱包在企微通过时置已退款,原路须渠道明确成功。
- 按官方契约实现微信直连 v3、微信 v2(双向证书)、富友(/commonRefund 与 /refundQuery)、
  支付宝四类原路退款;能力只由服务商类型与退款必需凭证完整性决定,无人工开关。
  渠道请求号在提交时冻结到尝试记录,并以 channel_submitted_at 条件认领保证资金动作至多
  提交一次(重复投递只查询不二次提交);不向任何渠道传递退款结果通知地址。
- 新增 refund:channel:recovery 恢复任务只查询回填;本地查询窗口超期(富友 72 小时、
  微信 v2 7 天)转原路退款失败、渠道状态已失败、分类超时未知并置异常转人工,不放行自动
  重提以避免重复退款。
- 同步退款 DTO/导出/审计资源与审计查询关联、商户凭证文档,并修正 fuiou 集成契约文档。

迁移 000218(退款尝试与渠道退款事实)、000219(微信 v2 客户端证书凭证)成对提供,
未修改既有迁移;测试库 junhong_cmp_test 完成 up/down/up 与行为核对,未调用真实渠道。
