1.1.0

🚀 UPC 1.1.0

Feature release adding card-alias payments (create-and-store, or pay with a saved alias) alongside
the existing hosted-fields flow, plus full/partial refunds against the Unified API.

✨ Added

• 💳 Pay with a saved card alias — new PaymentDto, sibling to HostedFieldDto, for paying
  with an already-created alias (no hfToken). Both share one PaymentRequestPayload contract, so
  UnifiedApiPaymentService::createPayment() accepts either.
• 🏷️ Create an alias from a hosted-fields payment — HostedFieldDto::$recurringMode +
  paymentMethod.saveFutureUsage create an alias for future reuse; PaymentOutput::$aliasId
  surfaces whichever alias was created or reused.
• 🏠 Billing/shipping support — BillingDto/ShippingDto, composing AddressDto/ContactDto/
  ShippingScheduleDto, wired into CommonFieldsDto.
• ↩️ Refunds — UnifiedApiPaymentService::createRefund() for a full or partial refund of a
  payment, validating accountId/orderId/description/submerchantExternalId locally before
  any HTTP call.

💥 Breaking

• UnifiedApiHostedPaymentService is removed; its method now lives directly on
  UnifiedApiPaymentService::createPayment().
• description is now sent unconditionally in every payment-creation request instead of being
  omitted when unset.

✅ Quality

PHPStan level 8, PHP-CS-Fixer, PHPUnit, and CI verifying PHP 7.1–8.2 compatibility — all clean on
this release branch.

📋 Requirements

• PHP ≥7.4 to install/develop (build-tooling floor only — shipped source runs on PHP 7.1)
• Runtime dependency: giggsey/libphonenumber-for-php
