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 Generated with [Devin](https://devin.ai) Co-Authored-By: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com>

+ * 1. HR 发起签署（校验组织电子签开关 + 自动渲染模板文件内容 + 创建证据链）
+ * 2. 员工在 portal 端查看待签文件 → 发送验证码 → 验证码确认签署
+ * 3. 签署完成 → 回写合同 + 追加证据链 + 生成签署确认文件
+ * 4. 易签宝回调（对接后启用）：更新状态 + 回写PDF
