fix: 修复二维码打印问题并优化标签布局

问题修复：
- 修复 qrcode() 函数不工作的问题，改用 sendcommand() 发送原始 TSPL 命令
- 添加 TSCLIB.sendcommand() 接口，支持发送原始 TSPL 指令
- 解决二维码静默区超出标签范围导致多打空白标签的问题
布局优化：
- 二维码位置从 (80, 120) 调整到 (70, 145)，上移避免静默区超出
- 二维码 cellWidth 从 3 增大到 7，提高扫码识别率
- 批次号字体从 20 增大到 24 并加粗，提高可读性
- 微调所有文本元素位置，优化整体布局对齐

技术细节：
- 二维码使用原始 TSPL 命令格式：QRCODE x,y,eccLevel,cellWidth,mode,rotation,"data"
- 添加调试日志输出二维码参数和 TSPL 命令
- QR 码静默区（Quiet Zone）约 4 个模块宽度，需预留足够底部空间
