- 新增 LabelData 模型统一聚合单张标签字段（qrBytes/copies 等） - 抽取 _renderLabelBitmap 共享位图绘制逻辑，TSPL 裸发与预览渲染完全一致 - 新增 renderLabelPreview / listLabelPrinters / detectDefaultPrinter 公开 API - printProductLabel 新增 printerName 参数，透传到热敏裸发路径 - 新建 LabelPreviewDialog：缩略图条+大图主视图，打印机下拉+记忆（SharedPrefs） 份数调整、勾选跳过、逐张打印进度状态显示 - 库存/商品详情/入库单 打标签 均接入预览弹窗，移除旧 _LabelPrintDialog Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
