Fixes 9 of 10 review findings (10th requires a manual Play Console step, no code change): 1. app.dart/banner_anuncio_superior.dart: move the top SafeArea inside BannerAnuncioSuperior so it only reserves status-bar height when an ad actually renders, restoring edge-to-edge layout for premium and free-unloaded users. 2. servicio_anuncios.dart: bound every interstitial await (load, presentation, and the injected implementation itself) with injectable timeouts so a callback that never fires can no longer hang a caller. 3. estado_entitlement.dart/hoja_premium.dart: expose a typed resultadoUsuario signal for purchase/restore failures and restore-found-nothing, with dedicated localized messages (compraError, restauracionSinCompras) across all 13 locales -- never the raw developer/exception string. 4. main.dart/servicio_consentimiento.dart: add a GDPR/UMP consent flow (ConsentInformation/ConsentForm) that gates Mobile Ads SDK init on canRequestAds(); premium users never see a consent form; failures degrade to no ads instead of crashing or blocking startup. 6. servicio_anuncios.dart: track real ad presentation (onAdShowedFullScreenContent) so a failed-to-show interstitial no longer consumes a session cap slot. 7. banner_anuncio_superior.dart: add an explicit load-attempted guard so repeated didChangeDependencies (e.g. entitlement notifyListeners during a purchase) can only ever trigger one banner load attempt. 8. servicio_anuncios.dart: make esPremium a required constructor parameter, matching the hardened contract already applied to EstadoAlarmas/EstadoGrabacion/EstadoRadio. 9. hoja_premium.dart: add a dedicated premiumActivo localized string instead of reusing the equalizer's equalizerActive translation, across all 13 locales. All fixes implemented RED-first (failing test before production code). Full suite: 1261 passed, 2 pre-existing skips, 0 failures. flutter analyze: 5 pre-existing issues only, 0 new. [version set]
