feat: implement comprehensive i18n system with German and English support

- Created type-safe i18n system with TranslationKeys interface
- Added German (de) and English (en) translations with 160+ keys
- Implemented I18nContext provider and useI18n hook
- Added LanguageSwitcher component for language selection
- Refactored all major components to use translations:
  * Home page, StatsDashboard, DramOfTheDay
  * BottleGrid, EditBottleForm, CameraCapture
  * BuddyList, SessionList, TastingNoteForm
  * StatusSwitcher and bottle management features
- Implemented locale-aware currency formatting (EUR)
- Implemented locale-aware date formatting
- Added localStorage persistence for language preference
- Added automatic browser language detection
- Organized translations into 8 main categories
- System is extensible for additional languages
