fix: prevent dialog crash caused by thread safety issues

[liyigang1]

1. Add thread assertion in DialogManager singleton:

   • Ensure DialogManager is only accessed from main thread
   • Add Q_ASSERT check for thread safety

2. Fix rename file operation issues:

   • Make needCheck parameter explicit in LocalFileHandler::renameFile
   • Pass correct needCheck flag in different rename scenarios:
     • Set to false for cut operations
     • Set to true for direct rename operations

3. Code style improvements:

   • Fix spacing in variable initialization
   • Improve code formatting for better readability

This fixes potential crashes when showing dialogs from non-main threads and improves rename operation reliability.

代码审查意见：

1. 在localfilehandler.h文件中，renameFile函数的默认参数needCheck被移除，这可能会导致调用该函数时没有传递needCheck参数而引发错误。建议在函数声明中保留默认参数，或者在使用该函数的地方明确传递参数。

2. 在dialogmanager.cpp文件中，添加了Q_ASSERT(qApp->thread() == QThread::currentThread());，这是一个好的实践，确保DialogManager实例在主线程中创建。但是，如果这个断言失败，程序会立即终止，这可能会导致用户体验不佳。建议添加错误处理机制，而不是直接终止程序。

3. 在docutfilesworker.cpp文件中，trashInfoUrl = trashInfo(fromInfo);和fileName = fileOriginName(trashInfoUrl);两行代码之间缺少空行，这违反了代码格式化规范。建议在两行代码之间添加一个空行，以提高代码的可读性。

4. 在docutfilesworker.cpp文件中，workData->currentWriteSize += (fromSize > 0 ? fromSize : FileUtils::getMemoryPageSize());这行代码中的三元运算符? :可以简化为std::max(fromSize, FileUtils::getMemoryPageSize())，以提高代码的可读性。

5. 在docutfilesworker.cpp文件中，bool skip{false};这行代码使用了C++11的列表初始化语法，但是false是一个字面量，而不是一个变量。建议使用bool skip = false;来初始化skip变量。

6. 在docutfilesworker.cpp文件中，if (fromSize <= 0)这行代码中的条件判断可以简化为if (!fromSize)，以提高代码的可读性。

7. 在docutfilesworker.cpp文件中，if (localFileHandler)这行代码中的条件判断可以简化为if (localFileHandler != nullptr)，以提高代码的可读性。

8. 在docutfilesworker.cpp文件中，return localFileHandler->renameFile(sourceUrl, targetUrl, false);这行代码中传递了false作为needCheck参数，这与localfilehandler.h文件中renameFile函数的默认参数不一致。建议在调用renameFile函数时明确传递参数，以避免潜在的混淆。

9. 在fileoperationseventreceiver.cpp文件中，ok = fileHandler.renameFile(oldUrl, newUrl, true);这行代码中传递了true作为needCheck参数，这与localfilehandler.h文件中renameFile函数的默认参数不一致。建议在调用renameFile函数时明确传递参数，以避免潜在的混淆。

以上是本次代码审查的改进意见，希望能够对您有所帮助。
