feat(survey-localization): add survey localization files for multiple languages

- Introduced new localization JSON files for Albanian, German, English, Spanish, Portuguese, and Chinese to support the survey feature.
- Each file includes translations for modal titles, button texts, and feedback messages to enhance user experience across different languages.
- Updated the SurveyPromptModal component to utilize these localization entries for improved accessibility and user engagement.
