/**
* FormCollect 的**FK 二级选择器**数据端点：外键字段（客户/产品/物料…）的候选从对应表实时取，
* 多列展示 + 名称搜索 + 分页。
*
* <p>前端渲染 {@code type=fkselect} 字段时调
* {@code GET /api/agent/form/options?table=elecustomer&q=..&page=1&pageSize=20}，
* 返回 {@code {columns:[{col,label}…], rows:[{sId, 列:值…}], total, page, pageSize}}。
* 安全：{@link FormResolverService#fkOptionPage} 只允许「在字段字典里作为外键目标出现过」的表，
* 并按名称字段模糊匹配 + 租户过滤 + LIMIT，避免任意读表。
