Refine property suggestion response handling in message processing

- Updated `process_message` to ensure property suggestions are only provided when the user has expressed interest and has a location preference, enhancing response relevance.
- Improved the formatting of property messages to include visual separators, making the output more readable and engaging for users.
- Ensured fallback messaging is clear when no properties are available, maintaining user engagement and clarity in communication.
