feat: 社保公积金独立配置+版本化缴费记录+月度增减员+补偿金批次

- Schema: 拆分社保/公积金配置，新增EmployeeSocialInsRecord/EmployeeHousingFundRecord/DepartmentRecord模型，扩展SalaryChangeRecord，增加SEVERANCE批次类型
- 后端: createEmployee/rehireEmployee接收社保公积金字段并创建缴费记录版本；createTermination/createResignation接收截止年月并关闭缴费记录；调薪/调部门API+版本记录；月度增减员API；公积金独立CRUD/计算/调基；SEVERANCE批次calcBatchEntry
- 前端: AddEmployeeModal/RehireModal增加社保公积金输入；ResignModal/Termination增加截止年月+日期不一致提醒；花名册增加调薪/调部门弹窗；SocialInsurance.tsx Tab拆分(社保/公积金/月度增减员)+CSV导出；Money.tsx增加补偿金批次类型
- 修复: seed.ts移除housingOrg/housingEmp；risk.service.ts从HousingFundConfig获取公积金费率
