Allow product content type to enable a mobile page layout for viewports below 892px

If the product's iframe is available (content type prop), use the full height of the viewport to display it in viewports below 892px. The website header has to be visible but the footer not.

The breakpoint is 892px which is the breakpoint in which the navigation menu in the header gets collapsed

Since these changes need to be applied to specific products (the daily dust product for now) add a field to the product content type to enable this feature.
