The premium sheet had no close affordance or way to defer, and its
copy only said "Función Premium" without stating what it unlocks.
Adds a header close (X) button and a "not now" secondary action so
dismissal is never harder than purchasing, and replaces the bare
title with a concrete, honest breakdown of the 5 things premium
unlocks (no ads, Android Auto, station recording, alarm vacation
ranges, unlimited alarms) plus the one-time-purchase framing. The
phone equalizer is never listed, since it stays free for everyone.
New l10n keys added to all 13 locales.
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.
