feat(bid): 新增历史报价参考功能并修复多租户与数据库约束问题

1.  为比价功能新增历史报价查询逻辑，当物料无当前RFQ报价时补充同物料其他RFQ的最近报价
2.  修复BizComparisonController的多租户ID获取逻辑，兼容无租户场景
3.  扩展报价单状态范围，将draft状态纳入有效报价统计
4.  新增发货单相关数据库表与修复脚本，修正biz_delivery_order的非空约束问题
5.  优化前端比价页面布局，移除旧的卡片式报价展示，统一使用表格展示
6.  修复类型转换与空指针风险，完善工具类方法的兼容性处理
7.  优化评分排序与徽章标记逻辑，避免覆盖自定义徽章
