feat: P4 dataSource 字段 + overtimePay 修复 + 获取按钮动态化

- schema: PayslipItem 增加 dataSource 字段标记数据来源
- DEFAULT_ITEMS: overtimePay 从 CALCULATED 改为 INPUT（修复被重算覆盖为0的bug）
- DEFAULT_ITEMS: performanceSalary/bonus/deduction 标记 dataSource
- 迁移逻辑: 已有组织自动补充 dataSource + 修正 overtimePay 类型
- 后端模板 CRUD 支持 dataSource 字段
- 前端模板编辑器增加数据来源下拉选择
- 前端模板表格增加数据来源列
- 前端批次详情'获取'按钮根据模板 dataSource 动态显示
