وابستگی PaymentController

// src/Payment/Controller/PaymentController.php
// متد subscriptionCallback() — بعد از تأیید پرداخت:

$subscriptionService->createFromPayment($payment, $periodUuid, $entityType, $entityId);

// این متد:
// 1. Period را پیدا می‌کند
// 2. expires_at را محاسبه می‌کند (در صورت تمدید از expires_at قبلی)
// 3. ClinicSubscription جدید می‌سازد
// 4. persist/flush
