feat(surveys): implement account setup survey functionality

- Added new database migration to create survey-related tables for storing questions and responses.
- Developed SurveyController to handle fetching and submitting survey data.
- Created survey API routes for account setup, including endpoints for retrieving the survey and submitting responses.
- Implemented frontend components for displaying the survey and capturing user responses, integrating with Redux for state management.
- Enhanced localization files to include survey-related text for multiple languages.
- Added validation middleware for survey submissions to ensure data integrity.
