Add viw_kg_edge_ref: ERP entity-reference (FK) graph (L3)
Parse gdsconfigformslave.sRelation (comma-separated field&table&pk&display hops) into FK edges: src_table.field -> tgt_table.pk, with the set of display columns each FK surfaces aggregated per edge. 1597 distinct FK edges / 368 source tables / 109 target tables (mostly ele*/sis* master data). Provides the join dictionary for NL2SQL grounding.

| 1 | +-- ============================================================ | |
| 2 | +-- 视图：viw_kg_edge_ref —— ERP 知识图谱·实体引用边 (ER/FK graph, L3, NL2SQL 接地) | |
| 3 | +-- 一条边 = 源表.外键字段 --引用--> 目标表.主键 (显示 显示字段) | |
| 4 | +-- 例：salsalesordermaster.sCustomerId --> elecustomer.sId (显示 sCustomerName) | |
| 5 | +-- | |
| 6 | +-- 边的来源：字段控件上的 gdsconfigformslave.sRelation | |
| 7 | +-- 格式 = 逗号分隔的多跳查找，每跳 `字段&关联表&主键&显示字段` | |
| 8 | +-- 单跳：sDepartId&sisdepart&sId&sName | |
| 9 | +-- 多跳(链式带出)：sEmployeeId&eleemployee&sId&sDepartId,sDepartId&sisdepart&sId&sName | |
| 10 | +-- —— 本视图取【第一跳】作为主外键边（源 = 该表单自身的数据表）。 | |
| 11 | +-- | |
| 12 | +-- 源表 = 字段所属主表单的 sTbName (gdsconfigformslave.sParentId → gdsconfigformmaster.sTbName)。 | |
| 13 | +-- 目标表多为主数据/字典表：ele*(员工/产品/客户/物料 等)、sis*(各类分类字典)。 | |
| 14 | +-- bTgtMaster=1 标记「引用到主数据/字典」，是 NL2SQL join 的关键信号。 | |
| 15 | +-- iFormCount = 有多少张表单声明了这条外键 —— 边权重/显著度，可用于排序召回。 | |
| 16 | +-- | |
| 17 | +-- 边粒度 = 一条外键 (源表.字段→目标表.主键)。同一外键在不同控件可带出多个显示字段， | |
| 18 | +-- 聚合进 sDisplayFields(逗号去重列表)，不拆成多条边。 | |
| 19 | +-- 表名统一小写作稳定节点id（MySQL 表名大小写不敏感；与 sDataSource 对齐）。 | |
| 20 | +-- 校验（本地库 xlyweberp_saas）：1536 条去重外键边 / 368 源表 / 109 目标表。 | |
