/**
 * 企业列表接口  GET/POST /api/company/list.php
 * v1.0.18 检索改造：
 * - field + keyword 联动：field=具体字段（如 name_zh/registration_number/…），keyword 只匹配该字段；field 为空=全部字段
 * - industry：行业下拉（精确匹配）
 * - company_type：企业类型（companies.legal_form，取自 data_dict_company_type）
 * 参数：page / limit / keyword / field / industry / company_type / is_active
 * 返回：{ list, total, page, limit }
