-- =====================================================================
-- v7 升级脚本: 合同分期缴费计划 + 签约负责人ID
-- 补充全量脚本 schema.sql 中新增、但现网库尚未执行的对象
-- 幂等: 建表用 IF NOT EXISTS, 加列先判断, 字典先删后插
-- =====================================================================

-- 3. 缴费计划状态字典(幂等: 先删后插)
-- 注: id 110-120 已被既有字典占用, 这里用 297-299(当前 max id 296 之后)
