When a user confirms a price from the modal, we now store it as an
"anchor price". On subsequent refreshes, if multiple price candidates
are found (common with variant products like different sizes/colors),
we select the candidate closest to the anchor price.
This fixes the issue where variant products would randomly switch to
a different variant's price on refresh.
Changes:
- Add anchor_price column to products table
- Save anchor price when user confirms a price selection
- Use anchor price to select correct variant on refresh
- 20% tolerance - if no candidate is within 20% of anchor, fall back to consensus
