What happended?

After performing partial payment captures on an order(via API), the fields order.summary.paid_total and order.summary.pending_difference do not update to reflect the actual captured amounts. These fields remain stale and show incorrect values, only considering the first capture.

Expected behavior

• order.summary.paid_total should sum all capture amounts (e.g., 500 + 200 = 700)
• order.summary.pending_difference should be the order total minus all captured amounts (e.g., 1330 - 700 = 630)

Actual behavior

• order.summary.paid_total shows only the first capture (e.g., 500)
• order.summary.pending_difference is calculated based on that incorrect value (e.g., 830)

Additional Context
The captures array within each payment correctly shows all capture records with accurate amounts, but the summary fields are not being recalculated after subsequent captures.

Temporary workaround:
We are manually calculating totals by iterating through order.payment_collections[].payments[].captures[] and summing the amounts.
