IAV-848/feat(credential): support SHOPIFY_ACCESS_TOKEN credential type
Add support for SHOPIFY_ACCESS_TOKEN as a distinct credential type alongside the existing SHOPIFY.
Changes in mapN8NTypeToCredentialType()
- Split the single
shopifycondition into two: one for standard Shopify API, one for access-token-based credentials (detected via"access"+"token"in the type string)
Changes in mapCredentialTypeToN8NType()
- Add
SHOPIFY_ACCESS_TOKEN → "shopifyAccessTokenApi"to the switch
Without this fix, any shopifyAccessTokenApi credential was silently downgraded to shopifyApi, causing N8N schema validation errors on creation, replication and token refresh.
