fix: enable antialiasing for photo/video buttons.

[add-uos]

The photo and video buttons were displaying with
blurry edges due to missing antialiasing settings in Qt6. The paintEvent method only set HighQualityAntialiasing for Qt5 and below, leaving Qt6 versions without any antialiasing. This fix adds proper antialiasing support for Qt6 using the standard Antialiasing render hint.

Reviewer's Guide

Extend photoRecordBtn paintEvent to enable QPainter antialiasing under Qt6, matching existing Qt5 behavior and eliminating blurry button edges.

我来对这个代码修改进行审查：

1. 语法逻辑：

• 代码语法正确，使用了条件编译来适配不同Qt版本
• 逻辑清晰，针对Qt5和Qt6+版本分别设置了不同的抗锯齿渲染提示

2. 代码质量：

• 优点：
  • 使用了条件编译确保跨版本兼容性
  • 代码结构清晰，易于理解
• 可改进点：
  • 可以考虑使用QPainter::RenderHint枚举值而不是字符串常量
  • 建议添加注释说明为什么需要区分Qt版本

3. 代码性能：

• 性能影响较小，因为这是在绘制事件中的设置
• 抗锯齿渲染会略微影响性能，但这是为了提升视觉效果所必需的

4. 代码安全：

• 代码安全性良好，没有发现明显的安全隐患

改进建议：

void photoRecordBtn::paintEvent(QPaintEvent *event)
{
    QPainter painter(this);
    
    // 设置抗锯齿渲染，适配不同Qt版本
#if QT_VERSION_MAJOR <= 5
    painter.setRenderHint(QPainter::HighQualityAntialiasing);
#else
    painter.setRenderHint(QPainter::Antialiasing);
#endif
    
    painter.setBrush(Qt::NoBrush);
    // ... 其余绘制代码
}

主要改进点：

1. 添加了注释说明版本差异的原因
2. 移除了多余的true参数（setRenderHint默认就是启用）
3. 保持了代码的缩进一致性

这些改动虽然不大，但能提高代码的可读性和维护性。
