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.

Amazon products can have multiple prices:
- Main buy box price
- "Other Sellers" prices
- Subscribe & Save prices
- New & Used prices
The scraper now extracts ALL prices, not just the main one. This allows
anchor price matching to find the specific price the user selected.
Also fixed AI verification overriding user's anchor price selection.
When user deliberately chose a price (e.g., "other sellers" at $52.91),
don't let AI "correct" it to the main buy box price ($79.99).
Changes:
- Amazon scraper now collects all price variants
- extractSiteSpecificCandidates handles allPrices array
- Anchor matching now always returns (no fall-through to AI override)
- Increased anchor tolerance from 10% to 15% for small sales
- Added debug logging showing all candidate prices

The previous logic checked preferred method first, which could select
a wrong price even when anchor price was available. Now:
1. PRIORITY 1: Anchor price - if user confirmed a price, find closest
match (within 10% tolerance) across ALL candidates
2. PRIORITY 2: Preferred method - only used if no anchor match found
3. PRIORITY 3: Consensus voting
Also added debug logging to trace anchor price saving and retrieval.

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
