Enhance Chat and Market Services with improved error handling and logging

Chat Service:
- Added detailed logging for API calls and responses, including warnings for missing authentication tokens and invalid response formats.
- Implemented a retry mechanism for message subscription setup on connection errors.
- Merged peers instead of clearing existing ones when loading from the API.

Market Service:
- Updated authentication checks to prioritize global auth state, improving user experience during order placement.
- Enhanced error messages for missing Nostr keys to guide users in configuring their profiles.

These changes improve the robustness and user-friendliness of the chat and market functionalities.
