ref(workflow_engine): Add legacy_notification_product column to workflow_engine.Action

[saponifi3d]

Description

While designing the NotificationActionHandler, we've run into a number of methods that are tightly coupled to the legacy product models. This will allow us to easily switch between the two registries and simplify which actions are available in the UI.

Also removes the NOTIFICATION generalized type in favor of specific types. This will allow us to more easily search / sort by these columns.
