Subject: [PATCH] feat(i18n): enhance dashboard with internationalization
 support

- Integrated `useTranslation` from `react-i18next` across various components for localization.
- Updated navigation, settings, and photo management components to utilize translation keys for labels and descriptions.
- Refactored error messages and user prompts to support multiple languages.
- Improved user experience by ensuring all relevant text is translatable, enhancing accessibility for non-English users.
