/**
|

* @file unsettled_order_mng.c
|
||
* @brief 未结算订单列表：EEPROM 持久化与 CRC 校验
|
||
*
|
||
* 功能说明：
|
||
* - 在 EEPROM `EEPROM_ADDR_UNSETTLED_MNG` 保存 `S_UNSETTLED_ORDER_MNG`：头标志 `UNSETTLED_HEADER`、
|
||
* 未结条数、以及除 CRC 字段外的 CRC-16 校验（与 `u16_calculate_crc` 一致）。
|
||
* - 每条未结订单仅保存其 Flash 订单号（`u32_chg_order_save_record` 返回的 `u32_index`）的 24 位压缩形式，
|
||
* 最多 `UNSETTLED_MAX_CNT` 条；列表按顺序追加，删除时前移尾部元素。
|
||
* - `u8_check_order_settled`：返回 1 表示该索引仍在未结列表中（未结算），0 表示不在列表中（视为已结或从未登记）。
|
||
* 命名与注释以头文件为准。
