fix: enable real-time volume adjustment in sound applet

1. Remove setTracking(false) calls from both SoundApplet and
   SoundQuickPanel
2. This restores the default tracking behavior that emits value changes
   during slider drag
3. Previously the tracking disabled prevented the volume from updating
   smoothly as the user dragged the slider
4. The volume now adjusts in real-time as the slider moves, providing
   immediate audio feedback

Log: Fixed volume slider not responding in real-time during adjustment

Influence:

1. Test volume adjustment by dragging the slider in the dock sound
   applet
2. Verify audio volume changes smoothly while dragging instead of only
   on release
3. Test the quick panel volume slider for the same real-time behavior
4. Ensure volume updates correctly when using keyboard shortcuts or
   slider steps
5. Verify no regression in volume slider functionality across different
   audio devices

fix: 修复声音调节不能实时变化的问题

1. 移除 SoundApplet 和 SoundQuickPanel 中的 setTracking(false) 调用
2. 恢复默认的跟踪行为，使滑块在拖动过程中持续发出值变化事件
3. 此前禁用跟踪导致音量在拖动过程中无法实时更新
4. 音量现在随滑块移动实时调整，提供即时音频反馈

Log: 修复音量滑块在调节时不能实时响应的问题

Influence:

1. 测试在任务栏声音组件中拖拽音量滑块
2. 验证音量在拖动过程中平滑变化，而不是仅在松开时更新
3. 测试快捷面板音量滑块的实时响应行为
4. 验证使用键盘快捷键或步进调节时音量更新正常
5. 确认在不同音频设备上音量滑块功能无回归

Reviewer's guide (collapsed on small PRs)

Reviewer's Guide

The PR fixes delayed volume updates by removing setTracking(false) from both sound sliders, restoring default continuous value-change events during dragging while leaving slider configuration otherwise unchanged; it also updates copyright year ranges.

💡 改进建议代码示例

// 本次变更已为正确的修复方式，无需额外代码示例
// 移除 setTracking(false) 即可恢复滑块实时跟踪行为

// soundapplet.cpp - initUi() 中已移除:
// m_volumeSlider->slider()->setTracking(false);

// soundquickpanel.cpp - initUi() 中已移除:
// m_sliderContainer->slider()->setTracking(false);
//
// Qt滑块默认 tracking=true，移除 setTracking(false) 后
// valueChanged 信号将在拖动过程中持续发射，实现实时音量调节
