Add typed JSON output to store authentication

[gonzaloriestra]

WHY are these changes introduced?

Fixes shop/issues-develop#23685.

Scripts need discoverable JSON contracts for store authentication and saved sessions.

WHAT is this pull request doing?

Shares session and associated-user schemas between auth, auth-list, and stored session summaries. The existing auth presenter validates JSON output; the hidden Stripe auth command shares the auth schema and retains its signup handoff protections.

The stack’s single minor changeset is included in #8585.

Example output

Illustrative sample data. Text excerpts omit terminal decoration and progress. JSON blocks show the final stdout result; progress and diagnostics go to stderr.

shopify store auth --store shop.myshopify.com --scopes read_products

Text

Logged in.
Authenticated as merchant@example.com against shop.myshopify.com.

To verify that authentication worked, run:
shopify store execute --store shop.myshopify.com --query 'query { shop { name id } }'

JSON (--json)

{
  "store": "shop.myshopify.com",
  "userId": "42",
  "scopes": [
    "read_products"
  ],
  "acquiredAt": "2026-09-18T10:00:00.000Z",
  "expiresAt": "2026-09-19T10:00:00.000Z",
  "hasRefreshToken": true,
  "associatedUser": {
    "id": 42,
    "email": "merchant@example.com"
  }
}

shopify store auth list

Text

Subdomain  Connected
shop       Sep 18, 2026

JSON (--json)

{
  "sessions": [
    {
      "subdomain": "shop",
      "connected": "Sep 18, 2026",
      "store": "shop.myshopify.com",
      "userId": "42",
      "scopes": [
        "read_products"
      ],
      "acquiredAt": "2026-09-18T10:00:00.000Z",
      "expiresAt": "2026-09-19T10:00:00.000Z",
      "associatedUser": {
        "id": 42,
        "email": "merchant@example.com"
      }
    }
  ]
}

The hidden store stripe-auth command uses the same auth result schema.
