Enhance chat and market integration with message forwarding

- Make ChatService globally available for other modules, enabling market-related message handling.
- Introduce a market message handler in ChatService to process market-related direct messages (DMs).
- Update useMarket to register the market message handler with ChatService, streamlining order-related DM processing.
- Refactor message handling logic to differentiate between market messages and regular chat messages, improving message management.
- Enhance order update logging in nostrmarketService for better debugging and verification of order status.
