Subject: [PATCH] Improve title field validation feedback in catalog edit form

Title field now validates on input, not just on blur. Added OnTitleChanged handler to clear validation messages for CatTitle as the user types. OnFieldChanged now only clears messages for UpdateProcedure. This enhances real-time validation feedback for users.
