Enhance ChatService to process market messages in chat

- Updated ChatService to forward market messages to the chat interface, ensuring they are displayed alongside regular chat messages.
- Improved message formatting for payment requests and order status updates, providing clearer user notifications.
- Deprecated the previous order updates subscription method in useMarket, redirecting functionality to the chat service for better integration.

These changes improve the user experience by consolidating message handling and enhancing clarity in communication.
