Fix window type for WEP and Advanced Protection dialogs above Settings

The previous window type FIRST_APPLICATION_WINDOW was incorrect and
caused the dialog to be dimmed and TalkBack to not be focused. The
current window type TYPE_APPLICATION fixes these issues by correctly
placing the dialog in the window hierarchy.
