feat: 系统优化Phase2 - 面包屑导航/侧边栏间距/制度公示阅读签收/模板变量中文化/通知类型补全

- 面包屑导航组件，集成至TopNav header
- 侧边栏菜单分组间距增大，分组间分隔线
- 制度公示员工阅读签收：PolicyReadRecord模型、portal路由、管理端阅读统计
- 修复Policies.tsx民主程序推进bug（字段名/API路径/参数）
- 用工文本模板变量名英文转中文显示
- 通知类型TYPE_LABELS补全(RISK_ALERT/SOCIAL_INS/OVERTIME_ALERT/PAYSLIP_READY)
- 通知示例数据补充
- h2标题统一为text-sm font-medium
- 新增run.md
