[Feature] Make the app name and activity labels translatable

[Jesse205]

The app name "Activity Manager" is not a proper noun and can therefore be translated into other languages. For example, it can be translated into Chinese as "活动管理器." Alternatively, to maintain professionalism, the Android-specific term can be retained, such as translating it as "Activity 管理器."

For example, most Google apps that are not proper nouns have corresponding Chinese translations:

Original Name	Chinese Name
Sheets	表格
Keep Notes	Keep 记事
Docs	文档
Files by Google	文件极客
Calculator	计算器
Photos	相册
Contacts	联系人
Translate	翻译
Camera Go	相机精简版

Only proper nouns remain untranslated, for example:

• Gemini
• Play
• Chrome
• YouTube
• Gmail

As for activity names, almost all activity names are not designated as proper nouns unless the activity represents a standalone app. Therefore, activity names should also be translatable.
