feat: 电子签署完整流程 + 证据链体系

## 后端
- esign.routes.ts 重写：
  - 发起签署时校验组织电子签开关（POLICY/PAYSLIP/ONBOARDING）
  - 自动从模板渲染文件内容（CONTRACT→劳动合同模板，RESIGNATION→离职协议模板）
  - 创建签署记录时自动创建证据链（发起签署事件）
  - 新增签署详情接口、证据链查看接口
  - 取消签署追加证据链事件
  - 签署状态查询自动处理过期记录
- portal.routes.ts 员工端 esign 重写：
  - 新增验证码发送接口（/esign/:id/send-code）
  - 签署操作增加验证码校验（5次错误限制）
  - 签署完成追加证据链（IP/UA/时间戳/验证码/签署人）
  - 签署完成回写合同 signMethod + attachmentName（签署证据）
  - 列表和详情接口自动处理过期记录

## 前端
- ESign.tsx 管理端重写：
  - 发起签署增加场景选择（5种场景）
  - 场景选择后自动填充默认文件标题
  - 新增签署详情页（文件内容预览 + 证据链时间线）
  - 签署流程说明
- MyEsign.tsx 员工端重写：
  - 签署操作增加验证码确认流程
  - 60秒倒计时限制
  - 文件内容预览
  - 签署完成状态展示
- api-services.ts：
  - esignApi 增加 detail/evidence 接口
  - portalApi 增加 esignSendCode 接口
  - signEsign 增加 verifyCode 参数
