feat(localization): add and update translations for multiple languages

- Introduced new localization files for Albanian, German, Spanish, Portuguese, and Chinese, enhancing the application's multilingual support.
- Added new keys and updated existing translations in project-view, task-list-table, and settings files to improve user experience across different languages.
- Enhanced error handling and empty state messages in task management components to provide clearer feedback to users.
- Updated tooltip texts and button labels for better clarity and consistency in the user interface.
