/**
* 在线支付编排服务（旺铺网关）
* 在线支付编排服务（渠道二选一：旺铺网关 / 微信官方支付）
*
* 链路：门店小程序选择账单合并付款
* → code2session 换 openid → 校验并锁定账单 → 创建支付单（pay_type=2）
* → 旺铺统一下单 → 返回调起支付参数 → 小程序 wx.requestPayment
* → 按当前渠道（site_config pay.online_channel）走旺铺统一下单或微信 JSAPI 下单
* → 返回调起支付参数 → 小程序 wx.requestPayment
* → 网关后台通知 / 小程序主动查询 → settle() 幂等结账：
* 支付单置成功 + 关联账单批量置已支付 + 累加门店总采购金额（只统计商品金额）+ 通知门店
*
* 已创建的支付单按自身 pay_method 固定在原渠道查询/结账（渠道切换不影响进行中的支付单）。
* 结账口径与后台「支付审核通过 / 线下收款登记」保持一致。
