fix: Handle Turkish İ character in product search

- Warehouse has 'MARLİN' (with Turkish İ) not 'MARLIN'
- Added Turkish character normalization in search
- Now correctly finds MARLİN 5 (2026) products in warehouse
- Found 6 Marlin 5 variants in warehouse

The issue was character mismatch: MARLIN vs MARLİN
