Use the system default language when unable to retrieve users

pms: BUG-286715

Summary by Sourcery

Use the system’s default locale as a fallback when user-specific language data is unavailable, and ensure translators are only installed upon successful loading.

Bug Fixes:

• Fallback to system default language when current user cannot be retrieved

Enhancements:

• Add installSystemTranslator to parse /etc/locale.conf and apply system locale
• Extract installTranslator helper and update initConnection to invoke system fallback
• Guard translation installation to only occur if translator.load succeeds

代码审查意见：

1. 在networkmodule.cpp文件中，installTranslator函数中增加了对translator.load的返回值检查，这是一个好的做法，可以避免加载失败时继续安装翻译器，从而避免潜在的运行时错误。

2. 在networkinitialization.cpp文件中，installUserTranslator函数中新增了installTranslator函数，这是一个合理的重构，将安装翻译器的逻辑分离出来，提高了代码的可读性和可维护性。

3. 在networkinitialization.cpp文件中，installSystemTranslator函数中读取/etc/locale.conf文件来获取系统语言，这是一个有效的方法来获取系统默认语言。但是，如果/etc/locale.conf文件不存在或者格式不正确，可能会导致函数返回默认值，这可能不是预期的行为。建议增加错误处理逻辑，例如检查文件是否存在以及内容格式是否正确。

4. 在networkinitialization.cpp文件中，installSystemTranslator函数中使用了QMap来存储locale.conf文件的内容，这是一个好的选择，因为它提供了方便的键值对操作。但是，如果locale.conf文件中的每一行都包含多个等号，那么split('=')可能会导致错误。建议在解析文件内容时增加适当的错误处理逻辑。

5. 在networkinitialization.cpp文件中，installSystemTranslator函数中使用了qCInfo来输出安装的系统语言，这是一个好的做法，可以帮助调试和日志记录。但是，如果这个函数在生产环境中被频繁调用，可能会产生大量的日志输出，建议根据需要调整日志级别。

6. 在networkinitialization.cpp文件中，initConnection函数中增加了对m_initilized的检查，这是一个好的做法，可以避免在初始化已经完成的情况下重复执行初始化逻辑。

7. 在networkinitialization.cpp文件中，initConnection函数中增加了对installSystemTranslator的调用，这是一个合理的改进，可以确保系统语言被正确安装。

8. 在networkinitialization.h文件中，新增了installTranslator和installSystemTranslator函数的声明，这是一个好的做法，可以保持接口的一致性。

总体来说，代码的修改和重构提高了代码的可读性、可维护性和健壮性。但是，还需要注意对错误处理和日志记录的适当调整，以确保在生产环境中能够正确运行。

Reviewer's Guide

This PR implements a fallback mechanism to use the system default locale when user‐specific language data cannot be retrieved by introducing new translator installation functions, updating the initialization flow to invoke them on failure, and refining the translator loading logic in the network plugin.
