Previously the action was logged unconditionally for every line item on
every payment confirmation, even when the price was identical to what was
already on the product. Now we compare unitPrice to the stored lastPrice
before deciding to record the change. New products being registered for
the first time are also excluded since that is not a price update.

Allow accounts to record partial/advance payments against a PO before
full delivery. A new PARTIALLY_PAID status tracks in-progress payment;
paidAmount accumulates across multiple markPaid calls. PO only closes
when both paidAmount >= totalAmount AND all line items are delivered.

PAYMENT_SENT: submitter only (it is a receipt prompt, not a manager action)
PARTIAL_RECEIPT_CONFIRMED: managers now notified via new event type
RECEIPT_CONFIRMED: unchanged (managers + accounts)
