Enhance authentication handling and error logging in ChatService and NostrmarketService

- Introduce a flag in ChatService to track initialization status and improve message handling.
- Enhance error handling and logging for API responses in ChatService, including warnings for invalid data formats.
- Update NostrmarketService to utilize global authentication checks, improving user authentication flow.
- Refactor CheckoutPage to streamline pubkey retrieval and enhance error messages related to Nostr identity configuration.

These changes improve the robustness of authentication processes and provide clearer feedback to users during interactions.
