Replace spaces with underscores in CSV column names

Update CSV export column headers to use underscores instead of spaces for better compatibility with data processing tools:
- Vendor Product number → Vendor_product_number
- Vendor code → Vendor_code
- Vendor name → Vendor_name
- Dealer product number → Dealer_product_number
- Zip code → Zip_code
