Embed support inside the Shopify customer account via Customer Account UI Extensions

[codeyogi911]

Outcome

A signed-in store customer can reach support without leaving their Shopify customer account:

• An Order status page block ("Need help with this order?") opens a support request pre-filled with that order's context and files it under the verified customer identity — no order number or contact card required.
• A profile-level page lists the customer's support requests with truthful status, backed by Desk case data.

Shape

• A companion Shopify app provides the Customer Account UI Extensions (order-status block, full-page list). The extension calls the deployment's Able instance with the customer-account session token; Able verifies the signed token, maps the customer to the same verified-actor seam introduced by Optional verified customer identity via Shopify customer-account sign-in #15, and serves bounded case data.
• Depends on and consumes Optional verified customer identity via Shopify customer-account sign-in #15's identity seam; this issue adds the embedded surface and the token-verified public API for case create/list scoped to the authenticated customer.
• Config-gated like every commerce integration: dormant unless the deployment supplies the app credentials via deployment secrets. Works with new customer accounts on standard Shopify plans.

Non-goals

• Replacing the standalone portal, anonymous intake, or capability links — customers without store accounts keep the existing flows.
• Any storefront theme surgery; the surface is the supported extension points only.

Sequencing: after #15.
