Before this commit o_row class wasn't applied on mobile because
we wanted that each field take all width.
But we have noticed that this class is quite well used on desktop
and is often used for specic cases that we also want on mobile.
Example: Unit of measure (UOM) next to a numeric field.
So in this commit, we simply removed mobile media queries.
Due to the number of places where this class is used, fixes will
surely follow.
