Subject: [PATCH] Update sample app to use QDeferredPurchasesListener

Replaces the deprecated QEntitlementsUpdateListener in the sample's
EntitlementsFragment with QDeferredPurchasesListener, which exposes
the full QPurchaseResult (entitlements, status, error). Toast messages
now branch on the purchase result status, and the related strings were
renamed to reflect the new listener.
