- Introduce new panel in the admin dashboard for displaying the least popular active cities. - Implement a database scope `least_popular_active` to retrieve cities based on their view counts. - Ensure compatibility with both SQLite and PostgreSQL for fetching city view data. This addition enhances the admin dashboard by allowing administrators to easily identify and manage cities that are receiving less user interaction, thus aiding in strategic planning for engagement and promotion.
