fix: show tray action icons during drag operations

[robertkill]

Added logic to make tray action icons (collapse/show stash) visible during drag operations over the tray area. When a drag event enters the tray container, the action icons become visible to provide better visual feedback. When the drag leaves without dropping, the action icons are hidden again to maintain normal UI state.

Log: Tray action icons now appear during drag operations over the tray

Influence:

1. Test dragging items over the system tray area
2. Verify action icons become visible when dragging over tray
3. Confirm action icons hide when drag leaves without dropping
4. Check that normal tray functionality remains unchanged
5. Test with various drag sources and file types

feat: 在拖拽操作期间显示托盘操作图标

添加了在拖拽操作期间使托盘操作图标（收起/显示隐藏）可见的逻辑。当拖拽事
件进入托盘容器时，操作图标变为可见以提供更好的视觉反馈。当拖拽离开而没有
放置时，操作图标再次隐藏以保持正常的UI状态。

Log: 托盘操作图标现在在拖拽操作期间出现在托盘上方

Influence:

1. 测试在系统托盘区域上方拖拽项目
2. 验证拖拽到托盘上方时操作图标是否可见
3. 确认拖拽离开而没有放置时操作图标是否隐藏
4. 检查正常托盘功能是否保持不变
5. 使用各种拖拽源和文件类型进行测试

Reviewer's Guide

This PR enhances drag-and-drop UX by toggling the tray action icons’ visibility during drag operations: it sets the "actionsAlwaysVisible" flag to true when a drag enters the tray area and resets it to false when the drag leaves without dropping, all within the TrayContainer component.

我来审查这段代码，并提供改进意见：

1. 代码逻辑和功能：

• 代码处理了拖放事件，通过设置actionsAlwaysVisible来控制动作图标的可见性
• 在拖拽开始时显示动作图标，在拖拽离开但未放置时隐藏动作图标
• 逻辑基本清晰，但有一些可以改进的地方

2. 语法问题：

• 代码语法没有明显错误，符合QML的语法规范

3. 代码质量改进建议：

• 添加注释说明actionsAlwaysVisible属性的具体用途和影响范围
• 将console.log(surfaceId, source)替换为更合适的日志方式，如使用Qt的日志系统
• 考虑将动作图标的可见性控制逻辑封装为一个独立函数，提高代码复用性

4. 代码性能改进建议：

• 当前的实现方式是合理的，没有明显的性能问题
• 可以考虑在不需要时及时清理资源，如确保Timer在不再使用时被正确停止

5. 代码安全改进建议：

• 建议对surfaceId和source进行有效性验证，确保它们不为空或无效值
• 考虑添加错误处理机制，防止在访问TraySortOrderModel时出现异常

改进后的代码建议：

Item {
    // ... 其他代码保持不变 ...

    // 拖拽进入处理
    onDragEntered: {
        surfaceId = dragEvent.getDataAsString("text/x-dde-shell-tray-dnd-surfaceId")
        source = dragEvent.getDataAsString("text/x-dde-shell-tray-dnd-source")
        
        // 验证拖拽数据的有效性
        if (surfaceId && source) {
            Qt.debug(`Drag entered - Surface ID: ${surfaceId}, Source: ${source}`)
            
            // 显示动作图标
            DDT.TraySortOrderModel.actionsAlwaysVisible = true
            
            if (source !== "" && DDT.TraySortOrderModel.isDisplayedSurface(surfaceId)) {
                dragEvent.accepted = false
            } else {
                dragEvent.accepted = true
                dropTrayTimer.restart()
            }
        } else {
            dragEvent.accepted = false
        }
    }

    // 拖拽离开处理
    onDragExited: {
        dropTrayTimer.stop()
        
        if (surfaceId) {
            DDT.TraySortOrderModel.setSurfaceVisible(surfaceId, false)
        }
        
        // 隐藏动作图标
        if (!isDropped) {
            DDT.TraySortOrderModel.actionsAlwaysVisible = false
        }
    }

    // ... 其他代码保持不变 ...
}

主要改进点：

1. 添加了数据有效性验证
2. 使用Qt的日志系统替代console.log
3. 改进了代码注释
4. 优化了条件判断结构
5. 确保资源被正确释放

这些改进可以提高代码的健壮性和可维护性，同时保持原有功能不变。
