doc: quick_start: edits from testing

Applied edits from testing the Quick Start app with @ketile.
Added information about how Developing with pages relate to other guides
in Application development.
Broke down testing steps for samples supported in Quick Start into
passive behavior that can be observed after programming using the app
and steps that require additional applications.
