Disable "Save Question" Button for Invalid Concept ID in Interactive Builder

In the interactive builder of Form Builder, when editing a concept ID in the schema editor, the system correctly checks if the entered ID exists and displays a notification if it does not. However, the "Save Question" button remains enabled even when an invalid or non-existent concept ID is entered. This allows users to save the form with an invalid concept ID, potentially leading to data inconsistencies.

Steps to Reproduce:

• Open the interactive builder in Form Builder.

• Edit the concept ID in the schema editor and enter an invalid or non-existent ID.

• Notice the notification indicating the concept ID is not present.

• Observe that the "Save Question" button is still enabled.

• Attempt to save the form.

Expected Behavior:
The "Save Question" button should be disabled until a valid concept ID is entered.

Impact:
Allowing the form to be saved with an invalid concept ID can lead to data integrity issues. This behavior should be fixed to enforce proper validation before saving.
