chore: remove touchpad switch file existence check

[fly602]

Removed the touchpad switch file existence check functionality from the mouse settings plugin. The implementation included:

1. Deleted touchpadSwitchFileExists() method from MouseModel class
2. Removed corresponding Q_PROPERTY declaration from header file
3. Eliminated visibility condition based on file existence in QML UI

This change was made because the touchpad switch file check is no longer needed in the current system configuration. The file path "/proc/ uos/touchpad_switch" was specific to a particular environment and the functionality has become obsolete with system updates.

Log: Removed touchpad switch file existence verification from mouse settings

Influence:

1. Verify touchpad settings page loads correctly without file existence check
2. Test touchpad functionality remains operational
3. Confirm no regression in mouse/touchpad configuration options
4. Validate UI layout consistency after removing the conditional visibility

chore: 移除触摸板开关文件存在性检查

从鼠标设置插件中移除了触摸板开关文件存在性检查功能。具体修改包括：

1. 从 MouseModel 类中删除了 touchpadSwitchFileExists() 方法
2. 从头文件中移除了对应的 Q_PROPERTY 声明
3. 在 QML 界面中移除了基于文件存在性的可见性条件

进行此更改是因为在当前系统配置中不再需要触摸板开关文件检查。文件路径 "/
proc/uos/touchpad_switch" 特定于某个环境，随着系统更新该功能已变得过时。

Log: 从鼠标设置中移除了触摸板开关文件存在性验证
PMS: BUG-342407
Influence:

1. 验证触摸板设置页面在没有文件存在性检查时正确加载
2. 测试触摸板功能保持正常运行
3. 确认鼠标/触摸板配置选项没有回归问题
4. 验证移除条件可见性后 UI 布局的一致性

Summary by Sourcery

Remove the obsolete touchpad switch file existence check from the mouse settings plugin.

Enhancements:

• Drop the touchpadSwitchFileExists property and associated method from MouseModel as the underlying proc file is no longer used.
• Always show the touchpad switch in the QML UI by removing its conditional visibility based on the deprecated file check.

Reviewer's Guide

Removes the obsolete touchpad switch existence check from the mouse settings plugin by deleting the backing C++ API and the QML visibility binding that depended on it.

File-Level Changes

Change	Details	Files
Remove the touchpad switch existence check logic from the MouseModel backend.	Deleted the touchpadSwitchFileExists() method implementation that used QFile::exists on /proc/uos/touchpad_switch. Removed the touchpadSwitchFileExists() declaration from the MouseModel class interface.	src/plugin-mouse/operation/mousemodel.cpp src/plugin-mouse/operation/mousemodel.h
Simplify the touchpad QML page by always showing the relevant switch control.	Removed the visible binding that depended on dccData.touchpadSwitchFileExists so the switch is now always visible.	src/plugin-mouse/qml/Touchpad.qml

我来对这段代码的变更进行审查：

1. 代码变更概述：

• 移除了MouseModel类中的touchpadSwitchFileExists()方法和相关的Q_PROPERTY声明
• 移除了Touchpad.qml中控制触摸板开关显示的visible属性绑定

2. 代码质量分析：
   优点：

• 移除了不必要的文件检查逻辑，简化了代码结构
• 删除了未使用的Q_PROPERTY，减少了不必要的属性暴露
• 提高了代码的可维护性

潜在问题：

• 这个改动可能会影响触摸板开关的显示逻辑。原本是根据"/proc/uos/touchpad_switch"文件是否存在来决定是否显示触摸板开关，现在直接显示开关，可能会导致在某些不支持触摸板的设备上也显示开关控件。

3. 安全性分析：

• 移除文件检查逻辑本身不会带来安全风险
• 但需要确保在所有支持的设备上都能正确处理触摸板开关的显示

4. 性能分析：

• 移除文件检查实际上可以提升性能，因为减少了文件系统访问
• 减少了不必要的属性绑定，也有助于提升QML的渲染性能

改进建议：

1. 如果确实需要移除文件检查，建议：

• 添加其他机制来判断设备是否支持触摸板
• 或者确保触摸板开关在不支持的设备上被正确禁用

2. 代码组织建议：

• 如果这个功能不再需要，建议添加注释说明移除的原因
• 考虑添加版本控制相关的注释，记录这个变更的背景

3. 测试建议：

• 需要在各种硬件配置下测试触摸板开关的显示和行为
• 特别要测试在不支持触摸板的设备上的表现

4. 文档建议：

• 更新相关文档，说明触摸板开关的显示逻辑变更
• 如果有相关的API文档，也需要相应更新

总结：
这个改动从代码简洁性和性能角度来看是积极的，但需要确保不会影响功能正确性。建议进行充分的测试，并考虑添加适当的注释说明变更原因。
