fix: Add Trek XML fallback for products not in warehouse

- When GPT-5 returns -1 (no match in warehouse), search Trek XML directly
- Fixes Marlin 5 showing wrong price (was showing Rail price)
- Now correctly shows 53,000 TL for Marlin 5
- Added debug messages for better troubleshooting

The issue was: Marlin products aren't in warehouse XML, so GPT was returning Rail index, causing wrong price/link.
