fix(bom-upload): 大文件性能优化 - 分页渲染+去重API匹配+进度条

问题：3993行Excel上传后页面崩溃
- DOM爆炸：3993行x39列=155K节点
- API风暴：3993行逐一调fetchSourceListPage

修复：
- 分页渲染：el-table只渲染当前页200行（DOM降至~8K节点）
- API去重：按唯一物料号去重查询，3993行→数百种物料，API调用减少90%+
- 进度条+可取消：el-progress显示匹配进度，支持中途取消
- 并发降为3，批次间200ms延迟避免浏览器卡顿
- 补充Excel列映射：合同批次/行项目号/投产批次
