settings: Hide status pages when not shown
We use a revealer to hide the status pages when not shown so they don't take any vertical space.
This allows us to use all the available vertical space when needed avoiding the nested scrolled windows. This should make selecting Wi-Fi networks in crowded spaces nicer as well as connecting BT devices when there's a long list.
This looks like a better solution than !1484 (closed) to me as we can use all the vertical space.
@arun-mani-j maybe you get a chance to test drive this?
