fix(chrome): drop the global AppBar, give each root its own title row

The prototype (t4) draws no global app bar anywhere: every root paints a plain ~56px title row inside its own content instead (Alarmas line 325, Ajustes line 511, Explorar line 641). app.dart wrapped every tab in PluriWaveScaffold(appBar: AppBar(title: Text(appTitle), ...)), adding 56dp of chrome and a "PluriWave" title the prototype never shows. Add PluriRootHeader, a shared 56px title-row widget reused by all 5 roots. Extract app.dart's old _mostrarTimerDialog (only reachable from the removed AppBar action) into a free function, showPluriSleepTimerSheet, so every root's header can open the same sheet directly and the sleep-timer feature stays reachable from every tab with no behaviour change. S1, Tier 1 visual-fidelity pass (audit id 2521).

+/// S1 (Tier 1 visual fidelity): the prototype (`t4`) draws no global
+/// `AppBar` — each root paints its own 56px title row inside its own
+/// content instead (e.g. Alarmas `height:56px;padding:0 12px 0 20px`,
+/// Ajustes `height:56px;padding:0 20px`, Explorar `height:56px`). This
+/// widget is that row, reused by all 5 roots so the sleep-timer action
+/// that used to live on `app.dart`'s single shared `AppBar` stays
+/// reachable from every tab.
