feat: 打通采购申请与入库的按单入库链路

后端变更: - PurchaseRequest 新增 base_id 硬关联 MaterialBase，StockBuy 新增 request_id 关联采购单 - handle_inbound 支持 request_id 入参，入库后自动反写采购单状态为已完成 - 新增 get_approved_requests 接口，返回已审批未入库采购单列表（含物料信息+历史数据回退匹配） - create_purchase_request 新增 name+spec_model 自动匹配 MaterialBase - 新增 SQL 和 Alembic 数据库迁移脚本前端变更: - 入库表单新增"从采购单导入"弹窗，支持搜索/选中已审批采购单并一键填充物料和商务信息 - 单价/总价交叉推算，缺项自动补全 - 选中行蓝色高亮+点击整行选中，行级交互优化
