fix(editor): disable voice reading when TTS service is unavailable

[tianming-1996]

Bug

https://pms.uniontech.com/bug-view-372251.html

问题现象

杀掉 uos-ai 进程后，文本编辑器未选中文字时右键菜单"语音朗读"未置灰，仍可点击。

根因

TextEdit::popRightMenu() 中，当 DBus 调用 com.iflytek.aiassistant 的 getTTSEnable 失败时（uos-ai 进程被杀，服务消失），错误处理分支直接 m_voiceReadingAction->setEnabled(true)，跳过了文字选中状态检查，导致"语音朗读"菜单项在未选中文字时仍可点击。

正常路径会检查 textCursor().hasSelection() && voiceReadingState，但 DBus 失败分支和无音频设备分支均无条件 setEnabled(true)，逻辑不一致。

修复

将 DBus 失败分支和无音频设备分支的 setEnabled(true) 改为 setEnabled(false)：服务不可用或无音频设备时，"语音朗读"功能无法工作，菜单项应置灰。

Reviewer's guide (collapsed on small PRs)

Reviewer's Guide

Adjusts the text editor’s context menu logic so that the 'voice reading' action is disabled when the TTS service or audio output device is unavailable, fixing inconsistent enablement behavior when uos-ai is killed or no audio device is detected.

File-Level Changes

Change	Details	Files
Align voice reading menu enablement with TTS service and audio device availability to prevent unusable actions from being clickable.	Change DBus failure branch for getTTSEnable to disable the voice reading action instead of enabling it. Change the no-audio-output-device branch to disable the voice reading action instead of enabling it. Preserve existing selection-based enablement logic for the normal path while making error paths consistent with actual capability.	src/editor/dtextedit.cpp

★ 总体评分：95分

■ 【总体评价】

代码修复了语音朗读按钮在异常情况下强制可用的问题，逻辑合理且无安全风险
修复了原有的状态判断缺陷，提升了用户体验和代码健壮性

■ 【详细分析】

• 1.语法逻辑（基本正确）✓

修改位于 src/editor/dtextedit.cpp 的 TextEdit::popRightMenu 函数中，将异常分支下的按钮状态从强制启用改为根据选中文本或列选状态判断，逻辑正确无误。
潜在问题：无
建议：无

• 2.代码质量（良好）✓

代码修改简洁明了，直接复用了现有的状态判断条件，符合代码规范，消除了原先可能导致无效操作的隐患。
潜在问题：无
建议：无

• 3.代码性能（无性能问题）✓

仅涉及简单的布尔逻辑判断和 UI 状态更新，不会产生性能瓶颈。
潜在问题：无
建议：无

• 4.代码安全（存在0个安全漏洞）✓

漏洞对比统计：新增漏洞 0 个，减少漏洞 0 个，持平 0 个
本次修改仅涉及 UI 控件状态控制，无外部输入处理或系统命令调用，不存在安全风险。

• 建议：无需额外安全修复

■ 【改进建议代码示例】

-            m_voiceReadingAction->setEnabled(true);
+            m_voiceReadingAction->setEnabled(textCursor().hasSelection() || m_hasColumnSelection);
