Unchained 5f9b7bac3a fix: set checkout languageCode to ensure emails are sent in correct language
- Add CHECKOUT_LANGUAGE_CODE_UPDATE mutation to update checkout language
- Call language code update before completing checkout
- Language code (SR, EN, DE, FR) is now set on checkout before order creation
- This ensures order confirmation emails are sent in the customer's language
- Update step numbering in checkout flow (now 6 steps total)
