[Woo POS][Surveys] Enable feature flag

[iamgabrielma]

Description

This PR enables POS Surveys in release builds.

Testing information

Testing one of the cases below is enough to assure the feature is enabled in release:

1. Switch the build configuration to release.
2. On a physical device, with notifications turned on, and in a US/UK store:
3. Update POSNotificationScheduler.timeIntervalInSeconds to something like 5 seconds
4. In AppCoordinator.schedulePOSSurveyNotificationIfNeeded add the following bit if needed to clear any persisted state from previous tests

private extension AppCoordinator {
    func schedulePOSSurveyNotificationIfNeeded() {
+        Task { @MainActor in
+          let action = AppSettingsAction.resetPOSSurveyNotificationScheduled { _ in }
+          stores.dispatch(action)
+        }
        Task { @MainActor in
            await POSNotificationScheduler(stores: stores).scheduleLocalNotificationIfEligible(for: .currentMerchant)
        }
    }
}

5. Case 1 - Potential merchant case: Navigate to Orders > create an order > observe the survey notification appearing. Creating a second order should not show the notification again.
6. Case 2 - Current merchant case: Visit POS once, restart the app, the notification should appear shortly.

• I have considered if this change warrants user-facing release notes and have added them to RELEASE-NOTES.txt if necessary.

@staskus no need to review this one from now, let's keep the feature flag on until we have final decision on the surveys.
