"""EXE 端到端验证(聚焦真实 BOM 模板支持):
1. 启动 MaterialWMS.exe
2. 登录
3. /boms 页面含 "批量导入窗口" + "Part Number" 真实格式说明
4. /template/bom 下载模板, 表头含 Part Number / Quantity
5. 生成多 sheet 真实格式 xlsx, POST /api/import/boms/preview (multipart) -> valid==2
6. POST /api/import/boms/commit -> created_materials >= 2
7. 校验 dist/app.db 中 Bom XM-A 存在
