[FEATURE] Add German Language Support
Is your feature request related to a problem? Please describe.
German-speaking users cannot use the application in their native language, limiting the application's reach in German-speaking markets.
Describe the solution you'd like
Add complete German language support:
- Translation Implementation:
- Create German translation files
- Translate all UI elements and messages
- Implement German-specific formatting (dates, numbers, etc.)
- Add German language option to language selector
Describe alternatives you've considered
- Using automated translation services
- Partial translation of critical features only
Additional context
- Depends on core i18n infrastructure implementation
- Should follow the established translation file structure
- Requires native German speaker review
