feat: 电子签全场景集成+场景筛选+设置开关

- ESignRecord 模型新增 scene 字段（CONTRACT/RESIGNATION/POLICY/PAYSLIP/ONBOARDING）
- Organization 模型新增3个电子签开关：esignPolicyEnabled/esignPayslipEnabled/esignOnboardingEnabled
- 设置页面企业信息新增电子签署设置区域，3个开关各自独立，缺省关闭
- 规章制度签收：开启电子签后，员工阅读确认时自动创建POLICY场景签署记录
- 工资条确认：开启电子签后，员工确认工资条时自动创建PAYSLIP场景签署记录
- 入职文件签署：开启电子签后，HR审批通过入职流程时自动创建ONBOARDING场景签署记录
- 电子签署列表增加场景筛选下拉（全部场景/劳动合同/离职协议/规章制度/工资条/入职文件）
- 管理端和员工端列表均展示场景标签（基于scene字段，替代硬编码判断）
- 合同和离职流程的esign调用已加scene参数
