feat(tender): 汇吉采标书购买 阶段3 - C端标书列表/详情/购买入口

- server/api/tender/{list.get,detail.get,order.post}.ts 代理到 mp-api /api/hjc/bid-project|order
- app/types/tender.ts 前端视图模型
- app/templates/template-07/pages/{TenderList,TenderDetail,BuyDocument}.vue（Tailwind，仿 Product 页）
- app/pages/tender/index.vue + tender/[id].vue + buy.vue 路由，经 useTemplate 加载
- useTemplate.ts 注册 TenderList/TenderDetail/BuyDocument（全部模板安全可选）
- 附 BUY_TENDER_MAP_REPORT.md（hjc-web 结构映射参考）
