Step-1-Result-Monad

[fmt-Println-MKO]

This pull request introduces the use of a Result Monad to improve the error handling and response handling for the orders data source. The key changes include:

• Implemented the Result monad for error handling throughout the orders service and data source
• Updated the GetOrder, GetAllOrdersForUser, and order storage methods to return monadic results
• Improved the order insertion logic in the orders data source
• Simplified the error handling and response handling in the orders service

These changes aim to provide a more robust and functional approach to handling errors and responses in the orders domain, making the code more maintainable and easier to reason about.
