Bundles views: adapt ENR creation and group classes

Converts 'rendering' group management classes and ExpandableNotificationRow
inflation to use entry adapters rather than NotificationEntry directly.

Additionally updates a couple of places in the pipeline to use pipeline data
structures directly rather than wandering into the 'render' package
