fix(transfer): 微信转账发起 AppId 回写落库, 确认收款查询凭证组装改用 buildTransferConfig 对齐发起路径

- WechatTransferStrategy 凭证组装后回写 wxAppId 到 TransferStrategyContext
- TransferAssistService.processing/mirrorProcessing 透传 wxAppId, 处理中镜像落库
- WechatTransferConfirmQueryService 改用 buildTransferConfig(查转账配置取发起应用), 与发起策略 buildCredential 一致
