feat: 优化退休提醒功能 - 个性化退休年龄计算

- 添加 FemaleWorkerType enum (CADRE/WORKER) 和 Employee.femaleWorkerType 字段
- 新增 calcIndividualRetireAge: 按个人出生日期逐人计算退休年龄
- 重写 calcRetirementDaysLeft: 基于个人出生日期+性别+岗位类型
- updateEmployeesRetirementDays 使用 femaleWorkerType 区分女干部/女工人
- 前端新增/编辑员工表单添加女性岗位类型选择器
- 前端政策展示改为改革规则卡片(基准→目标年龄)
- 前端距退休天数改为退休日期显示(XXXX年XX月XX日)
- 移除AI退休政策计算相关代码和手动刷新路由
- 导入支持女性岗位类型列
