Use Canva autofill jobs when content must be populated into a design

For Canva workflows that need content inserted into a generated design, do not rely on the create-design endpoint/tool. CANVA_CREATE_CANVA_DESIGN_WITH_OPTIONAL_ASSET is deprecated and should be replaced with CANVA_POST_DESIGNS, but both the old and new create-design flows create a blank design by default and do not accept arbitrary content in the request. Use CANVA_INITIATE_CANVA_DESIGN_AUTOFILL_JOB for the content-population use case, because that flow is built around Canva's autofill capability.
