Validate an EU VAT ID against the official VIES (VAT Information Exchange System) API from the European Commission.
Returns validation status along with company name and address when available.
The service strips the country code prefix from the VAT number before validation if present
(e.g., 'PL5252678750' becomes '5252678750' when validating for country 'PL').
