Gifts to Review - missing designation backend ID

For GiveCampus integrations and API.

Open the affected gift error and enter the correct NXT fund backend/lookup identifier for the indicated designation, confirmed by the CRM administrator. The resolver validates the fund and updates the gift split. Choose the scope deliberately: the current row, other affected gifts in the batch, and/or the school-level designation for future gifts. Save and verify the error/export result. Do not invent IDs or create duplicate gifts to bypass the mapping error.
