Detailed Description

Owns the application QTranslator instances and provides language metadata.

Encapsulates all translation concerns: discovering available .qm files, loading/unloading QTranslator objects, and mapping language codes to display names and flag icon resource paths. Emits translationChanged() after each successful load so the UI can retranslate itself.
