feat: enhance message retrieval logic with context-based filtering

- Updated the MessageSchema to include context-aware filtering for notifications, allowing retrieval of messages based on recipientId when the context is NOTIFICATION.
- Improved the resolve function to handle subscription checks, ensuring that unauthorized access is properly managed.
- Added error handling for cases where the context is not allowed, enhancing overall robustness of the message retrieval process.
