theme: OSK opaque

- the on screen keyboard is not an overlay in most cases. the semi-opacity is distracting. - use opaque background color - see discussion on https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/1028 FIXME: whitespace at the bottom without scaling everything down (padding) FIXME: don't behave as overlay anywhere (even for entries above the fold)
