feat(escuchar): replace discovery browser with embedded player and favorites grid
Restructures PantallaInicio's top of screen: a new _EscucharHero (square art, live/offline pill, VisualizadorAudio at barras: 30 / altura: 26 / color: liveGreen, a 5-action transport row - favorite, EQ toggle, stop, play/pause, sleep - plus a tool-tray entry chip opening the full player) replaces the old PluriScreenHeader hero, and a new "Tus emisoras" section (favorites preview, capped, "Ver todas") follows it. Per design ADR-7, EstadoRadio stays the single source of truth: the hero is a StatelessWidget with no cached fields, reading emisoraActual via context.select (uuid-based equality scopes rebuilds to real station changes) and the fast-changing playback status via StreamBuilder, the same pattern _Controles/MiniReproductor already use. The still-present discovery sections (_seccionCercanas onward, including the old grid) are deliberately left in place - WU6 relocates them to Buscar and deletes them from here; removing them now would leave that content nowhere until WU6 lands. MiniReproductor gains a `visible` parameter (default true) and a measured `static const double altura`. app.dart passes `visible: indice != RaizPluriWave.escuchar.index`, hiding it visually only (SizedBox.shrink()) while Escuchar is active, since the hero already shows the same station - the State stays mounted so its didChangeDependencies side effect (configurarLocalizaciones, S3-R3) keeps running regardless of tab. altura was measured empirically (72.0, via tester.getSize) rather than guessed, backing a new derived PluriLayout.escucharBottomChromeInset constant now wired into PantallaInicio's own bottom padding. "Ver todas" switches roots via EstadoNavegacionRaiz.irA(favoritos), verified via a NavigatorObserver asserting the push count is unchanged (switches tabs, does not push). Fixed a pre-existing test-infrastructure gap while writing the anti-cache test: no test in this codebase had ever exercised ServicioAudio.androidAudioSessionIdStream against a bare FakeServicioAudio (pantalla_reproductor.dart has always read it but has no test file at all) - the real getter needs registrarHandler() (main.dart, production only) and threw otherwise. Added an empty stream override to FakeServicioAudio, matching VisualizadorAudio's own documented no-native-session fallback. Tests: 614 -> 618 (2 skipped, unchanged). flutter analyze unchanged at 1 pre-existing info. git diff empty for visualizador_audio.dart and estado_radio.dart - this WU touches neither.
