feat: preserve manual component data if code unchanged

[italojohnny]

This PR updates the backend logic to preserve certain fields (display_name, description, and tool_mode) of frontend components when their code has not been modified. This ensures that user-provided values are not overwritten unnecessarily.

Frontend adjustments will be required to properly utilize the preserved data.

Nice! I think we will just have to change it so that the parameters are maintained when the user updates the code manually as well. Also, could you maybe implement a logic to just update the description if the description of the new code is different than the description of the old code please?
Thanks!
