Change of user language

[kruscho]

Hi,

Currently, language settings may be auto-detected or tied to system defaults. This can lead to mismatches between user preferences and the interface language, especially in multilingual environments or for users working across regions.

Introduce a dropdown or toggle in the profile tab that allows users to manually choose their preferred language from a predefined list (e.g., English, German, French, etc.). This setting should override any automatic detection and persist across sessions.
