Simplify mobile-sticky ad styles

[cemms1]

What does this change?

Uses the full width design for all mobile-sticky ads across the site rather than using a particular design for some scenarios and not for others

This combines the full width styles with the general styles and removes unnecessary props from the MobileStickyContainer which specify content type

Additionally updated all mobile sticky containers to only render when renderAds is true, since we don't want the slot appearing at all in the DOM where we don't show ads.

Why?

We discovered we were only using the full width designs on certain article types recently and would like a consistent approach across all mobile sticky slots on the site

We already control whether the mobile sticky slot is eligible to be filled in the commercial bundle so the only thing DCR needs to know is how to style the resulting ad slot
