feat: 最低工资保护 + 社保/最低工资递延补扣机制

Browse Source 
新增功能：
1. SocialYearStandard / SocialInsuranceConfig 增加 minWage 字段
2. BatchEntry 增加递延扣款字段（deferredSocialEmp/HousingEmp/MinWage）
3. calcBatchEntry 增加最低工资保护逻辑：
   - 实发 < 最低工资时，优先递延社保 → 递延公积金 → 递延最低工资补齐
   - 递延金额记录到 BatchEntry，次月创建批次时自动补扣
4. prePayrollCheck 增加最低工资检查（第 11/12 项）
5. 前端社保配置增加最低工资输入框
6. 前端 BatchTab 质量门禁增加最低工资/递延扣款提示

处理场景：
- 入职当月工资不足扣社保个人部分 → 递延到次月补扣
- 实发低于最低工资 → 补齐到最低工资，差额递延次月扣
- 次月创建批次时自动读取上月递延金额并补扣
