Enhance market DM decryption process with improved authentication checks

- Introduced checks for both injected auth service and global auth composable to retrieve user private and public keys.
- Enhanced logging to provide clearer feedback on authentication status during DM decryption attempts.
- Improved error handling for cases where user keys are unavailable, ensuring better user guidance.

These changes strengthen the authentication flow and improve the reliability of market-related direct messages.
