Include author on product prices
Description
Include an author node on fixed and unit prices, to track who created them.
This will store the user id in a details node, as an interim solution until create/update users are stored in actual database columns. It is therefore not ideal for reporting on but:
can be used to display the user name in the UI
can be migrated when the database model changes
It will need to be populated when editing and importing prices, and when new prices are created by delivery processing
Environment
None
