Skip AI verification when multiple price candidates exist

When the scraper finds multiple valid prices (e.g., Amazon main price +
other sellers), skip AI verification entirely. AI was "correcting"
valid alternative prices to the main buy box price.

Now with multiple candidates, users see all options in the modal and
choose themselves - no AI interference.
