+   工作流补丁：恢复缺失的「筛选唯一索引」
+   ------------------------------------------------------------
+   背景：现有 G3ERP 库的 wf_* 表已建，但基础 DDL 里的 4 个筛选唯一索引
+   （unique filtered index）在库中并不存在。缺了它们意味着：
+
+     - 同一定义可以并存多条草稿（应用层靠代码判，DB 层无兜底）；
+     - submit 的幂等键 b_idempotency_key 不生效 —— 重复提交不会被拦；
+     - wf_action.b_request_id 不生效 —— 重复审批不会被拦；
+     - 同一模块/事件下可以有两条同优先级启用绑定。
+
+   本脚本幂等；创建前先查重，有冲突则 RAISERROR 报错而不是静默失败。
