Add Shopify pull-from feature and fix product creation payload

- Add "Aus Shopify laden" button on product edit page that pulls description
  and variant prices/SKUs/GTINs from Shopify back into SMS
- Add ShopifyService::getProduct() for fetching a single product
- Add 'options' to createProduct() payload so Shopify properly creates variants
  (without it Shopify ignores variant option values)
- Add request/response logging to createProduct() for diagnosing transfer issues
- Remove dead code from ProductResource (mutateFormData*, getRecord, getActions)
- Clean up imports in ProductResource
