feat: enhance city description generation

- Modify get_description method to include an additional
  parameter for user context
- Update usage in views to reflect the new parameter
- Adjust temporary description message based on user context

This change enhances the city description generation logic by
allowing differentiation in how the description is provided
depending on whether the calling context is a user. It improves
the user experience while ensuring that non-user contexts
handle descriptions differently. This minor enhancement also
included updating the view to support this new logic.
