Support references on errors, checkout redesign and API settings

Support reference on server errors

When something breaks, the masked error a merchant sees now carries a support reference. Send that code along and support can trace the exact failure in the logs instead of reconstructing it from a screenshot.

Checkout redesign

Checkout moved to a split layout with wallets up front and delivery ETAs shown against each shipping method, and addresses autocomplete through Google Places so buyers type a line instead of a form. An appearance editor in the admin previews your changes live before shoppers ever see them.

API settings with one persistent store key

The API settings page was rebuilt around a single persistent Vercel key per store, so there are no duplicates to juggle and no doubt about which key your integrations are actually running on.
