fix: 统一风险中心及全应用身份证号显示

后端：
- employee.routes.ts: all-lite 接口加上 idCardNumber 并解密
- special-status.routes.ts: 列表和详情查询加上 idCardNumber 并解密
- esign.routes.ts: 列表/pending/detail/remind 接口加上 idCardNumber 并解密
- risk.service.ts: getMonthlyCalendar 所有事件加上 employeeIdCardNumber
- termination.service.ts: batchTerminatePreview 加上 employeeIdCardNumber
- employee.routes.ts: preview-renew 加上 employeeIdCardNumber

前端：
- Roster.tsx: 批量续签/解聘预检结果加上身份证号
- SpecialStatus.tsx: 列表/下拉/删除确认加上身份证号
- Calendar.tsx: 日历事件姓名后显示身份证号
- ESign.tsx: 签署列表/详情/员工列表/提醒弹窗/下拉加上身份证号
- CommercialInsuranceTab.tsx: 参保选择列表加上身份证号
- OvertimeTab.tsx: 导入预览加上身份证号
