fix: Add validation for MessageBase type in message input conversion

[ogabrielluiz]

This PR introduces validation for the MessageBase type within the message input conversion process. It ensures that if an instance of MessageBase is provided, it is correctly transformed into a Message object using the model's data. This enhancement improves the robustness of input handling in the application.

This helps when you create a component, call send_message passing a Message and then return the result of the call (which now is a MessageRead, not a Message anymore).
