help-docs: Standardize on "corner of the app" instead of "...screen".

The phrasing "corner of the screen" wouldn't be accurate when the user
is doing a split screen or if the window or app is not taking up the
whole screen. Also, the use of "lower/upper" and "top/bottom" is not
consistent.

This standardizes on "corner of the app" and "bottom/top" when
referring to the location of app features on Desktop, Web, or Mobile.
