fix(qa): ISSUE-002 — ROA prices not showing in order detail modal

The JS read pret_roa from order.price_check.items[idx] which doesn't
exist. The backend puts pret_roa and price_match directly on each item
in the items array. Fixed both desktop table and mobile view to read
from item.pret_roa and item.price_match instead.
