/**
|
* 结算记录查询的两个真实约束。
|
*
|
* <p>一是通道对 {@code pageSize} 的上限：实测传 51 或 100 会返回 {@code 00000003}
|
* 「基础参数校验失败:【pageSize-分页条数】不能为空，且最小值为0，最大值为50」，
|
* 一条流水都拿不到。后台「结算记录」页原来默认传 100，于是页面永远空白——通道里其实有流水
|
* （商户 6666000226048687 在 2026-08-26 / 08-29 各结过一次）。所以越界值必须在网关内收敛。
|
*
|
* <p>二是回执解析：结算流水以 JSON 字符串放在 {@code trans_log_result_list} 里，
|
* 翻页总数在 {@code result_count}。这两处解析错了，后台同样看不到流水。
