Make Saved Accessions information available to donor users

[HaSistrunk]

Is your feature request related to a problem? Please describe.

It would be useful for donors to be able to see the status and details about accessions.

Describe the solution you'd like

• In the redesigned Aurora (PR Implement RAC Style Library #667 ), add the Saved Accessions page to the header navigation under the "Transfers" menu for non archivist users
• Figure out how to create a different view on that page for donors v. archivists that only shows accessions from that donor organization and does not give donors the ability to trigger incomplete accessions.

Additional context

This is a feature that the Collections Management staff have affirmed would be useful for donors to see which transfers were accessioned. This is related to issue #694 .
