fix: Add phone number fields to WooCommerce cache tables #30

- Created database migration to add phone fields
- Added phone column to woocommerce_customers_cache table
- Added customer_phone column to woocommerce_orders_cache table
- Updated woocommerce-sync function to extract phone numbers from billing data
