refactor: replace generateTenantCode boolean with tenantPaymentMethod enum

- Replace generateTenantCode boolean field with tenantPaymentMethod enum ("none" | "iban" | "revolut")
- Update LocationEditForm to use dropdown select instead of toggle for payment method selection
- Consolidate multiple useState hooks into single formValues state object
- Change from defaultValue to controlled components with value/onChange pattern
- Add hidden inputs to preserve tenant data when payment method is not selected
- Update validation logic to check tenantPaymentMethod === "iban"
- Update ViewLocationCard to use new tenantPaymentMethod field
- Add Croatian translations for new dropdown options

This provides better scalability for adding future payment methods and improves form state management.
