Fix: re-read Sales Header from DB after RedistributeInvoiceDiscounts

Replace the IsCompletelyShipped save/restore pattern with Rec.Find()
after RedistributeInvoiceDiscounts. This re-reads the entire Sales Header
record from the database, ensuring all fields including Completely Shipped
reflect the true persisted state regardless of any in-memory side effects
from the invoice discount redistribution call chain.
