/**
|
* 个人（小微）主体的 MCC 取的是**商户在进件表单里选的行业**。
|
*
|
* <p>进件第一步让个人商户选「行业类型」（餐饮服务／酒店服务／景区服务／加油服务／停车服务／其它），
|
* 它跟着企业主体的公司类型一起落在 {@code company_type} 列上。原先上报汇付的 {@code mcc}
|
* 只认商家档案上的经营类型，等于把这一项**静默丢掉**：档案没配好就一律落 7399（其它），
|
* 通道侧的微信行业类目和费率跟着一起错，而商户页面上明明选过行业。
|
*
|
* <p>「其它」与识别不出来的取值返回空串，交给商家档案兜底——不要在这里拍一个 7399，
|
* 那会把「档案里配了准确行业」的商户也降级成「其它」。
