📝 Implementation

• Added a new computed property to QuestionnaireQuestion
  • This property is set to true when an "assign" action from a program rule sets the question value, otherwise false.
• Disable the QuestionWidget if computed value is true
• Why a new property?
  • Allows reverting the "disabled" state in the view
  • Prevents unintentionally enabling a field that was disabled due to other conditions
