fix(scrap): 报废申请页搜索/选择解耦，审批人常驻必填

一、搜索丢失已选（核心 bug）
主表格 :data="stockList" 同时充当搜索结果与选择容器。Element Plus 的
setData 在 reserveSelection 为假时走 clearSelection()，进而 emit
selection-change([])，故每次重新搜索都会清空选中态、「已选 N 条」归零。
（源码路径：table/src/store/index.mjs:34-52 → store/watcher.mjs:145-152）

改为「购物车 + 选择弹窗」结构，对齐出库选单页：
  · 主表格数据源改为 cart（已选清单），删除复选列，改「移除」按钮；
  · 新增「选择库存物品」弹窗，搜索框移入其中；
  · 表格 row-key + :reserve-selection="true"，跨搜索/翻页保留勾选；
  · 点行勾选、改数量自动勾选、数字框 @click.stop 防冒泡反转勾选；
  · 服务端搜索（350ms 防抖）+ 分页 20/50/100/200；
  · uniqueKey 取 source_table_id（三表主键各自独立，必须带表名前缀）。

二、审批人字段不显示
原为 v-if="approvalVisible"，仅库管代建或命中需审批物料时才渲染。
因全库仅 1 个物料标记 is_approval_required，该条件几乎从不成立。
现改为常驻，并用 el-form rules 声明 approver_id / remark 双必填；
打开弹窗即调用 checkScrapApproval 预检并展示提示文案。

三、顺带修复
库位列此前恒为空：三张库存表 to_dict 只输出 warehouse_loc，而模板绑定
warehouse_location。已在 loadStockList 中归一化。

SFC 编译与 vue-tsc 通过，无新增类型错误。
