Overview

Copies ActiveStorage attachments when a record is duplicated, e.g. for copy-on-write. Pending changes on the source are carried over: new uploads are copied to the duplicate, while attachments that are being removed (either by assigning "" as govuk_attachment_field does, or via nested attributes with _destroy) are dropped from the duplicate.
