- Integrated translation functionality into existing components (TaskStatusDropdown, Navigation).
- Created LanguageSwitcher component for language selection.
- Updated task statuses and navigation labels to use translations.
- Added Polish translations for various UI elements, including navigation, tasks, projects, and contracts.
- Refactored utility functions to return localized strings for deadlines and date formatting.
