Support digital items and fulfillment

[pbennett1-godaddy]

Summary

Adds digital-fulfillment support to the React checkout flow.

Previously, digital-only and mixed digital carts could be treated like physical fulfillment carts, which could surface delivery/shipping/pickup UI, trigger fulfillment sync for digital line items,
require missing shipping information, or collect the wrong billing/tax fields. This PR makes checkout fulfillment-aware so digital-only orders skip physical delivery flows while still collecting the
billing information needed for tax and payment.

Key updates include:

• Detect digital, non-digital, pickup, purchase, and digital-only line item fulfillment.
• Derive DIGITAL as the checkout delivery method for digital-only orders.
• Hide delivery, shipping, pickup, and express checkout sections for digital-only orders.
• Prevent custom layouts from forcing unavailable delivery or express sections.
• Gate express checkout to supported physical shipping flows.
• Ignore digital line items when syncing missing shipping or pickup fulfillment.
• Avoid blocking digital checkouts on missing shipping information.
• Collect the correct billing information for paid, free, taxable, and offline digital orders.
• Use billing address for tax recalculation on digital and purchase flows.
• Improve line item image rendering by falling back to a placeholder for invalid asset IDs.
• Add auto-resizing behavior for checkout notes textareas.

Test Plan

Ran the React package test suite focused on the changed checkout areas:

pnpm --filter @godaddy/react test -- src/components/checkout/__tests__/checkout-digital-fulfillment.test.tsx src/components/checkout/__tests__/checkout-validation.test.tsx                             
src/components/checkout/line-items/line-items.test.tsx src/components/checkout/pickup/local-pickup.test.ts src/components/checkout/shipping/utils/should-apply-shipping-method.test.ts                    
src/components/checkout/utils/checkout-transformers.test.ts
