fix: undo all of the margin hacks

Using 72dp as the height appears to have been a bit of a hack to appear beyond the navigation bar. In cases where the bar is not present, such as landscape, this left a gap between the bottom of the screen and bar. On API 23, the result was the opposite. All of this can be addressed by simply relying on the actual measurements and not compensating for compensation.
