Subject: [PATCH] Add competitor benchmark pricing and profit optimization

Features:
- Fetch competitor benchmark prices from Google Price Competitiveness Report
- New get_all_benchmark_prices() method in Google API class
- Display competitor price instead of own Google price
- Calculate recommended price (slightly below competitor)
- Show potential gain/loss per product if price is optimized
- Color-coded status:
  - Green: Your price is cheaper (opportunity to increase)
  - Blue: Competitive (within 2% of competitor)
  - Red: Expensive (above competitor)
- Summary statistics showing:
  - Products with benchmark data
  - Count by status (cheaper/competitive/expensive)
  - Total potential gain if all prices optimized
