## Description

Adds a VAT field to the WooCommerce checkout page (both classic and blocks). Validates
the entered VAT number using the Zebby VAT API (https://api.zebby.io) and displays
the result. Optionally allows for VAT exemption based on validation status and country
rules.

Features:
 * Adds VAT field to classic & block checkout. * Real-time validation 
via AJAX (configurable). * Displays validation success/failure/error messages. *
Displays company name if provided by API. * Configurable API key and endpoint URL.*
Option to enforce VAT field requirement. * Option to enable automatic VAT exemption
for valid numbers in specific countries. * Dedicated settings page. * Debug logging

–
VAT number (required for validation) – Country code (to determine applicable VAT
rules) – (Optionally) Company name, if provided by the user

This data is used solely to validate the VAT number and determine VAT exemption 
eligibility during checkout. No other personal or sensitive data is sent.
