Rename ReadImageView -> ShowImageReadView

We also remove AppointmentMixin so that we no longer rely on an
appointment pk passed in the URL. The view now picks an arbitrary
appointment with a study attached as dummy data, with a TODO marking it
for replacement once retrieval of the appropriate Reading object is
implemented.
