feat(reproductor): restructure full player with tool-tray and EQ sheet

Restructure pantalla_reproductor.dart onto PluriPushScaffold (design
ADR-2 - this screen is the documented single consumer of titleOverride,
a centered live/not-playing status pill, and the non-default
keyboard_arrow_down leadingIcon). Square art replaces the old circular
hero, favorite moves from the AppBar into the transport row (the
redundant live-indicator dot is dropped - the AppBar pill already covers
that signal), the old separate info chips collapse into a single
subtitle line, and a new quality row surfaces codec/bitrate with a
"Cambiar" action that reconnects the current stream (this app has no
per-station alternate-quality capability to invoke, so this reuses the
same reproducir() call the existing error-state retry button already
uses, rather than a dead button or an invented picker).

The always-expanded recording panel and the standalone sleep-timer
button both become tool-tray tiles (EQ propio / Grabar / sleep timer /
Compartir), each opening its own bottom sheet. "EQ propio" opens a sheet
hosting EcualizadorWidget - the exact same component WU13 restyled for
Settings, bound via the existing presetParaEmisora/guardarPresetPorEmisora
per-station persistence path. No second editor was created; the
multi-device-eq resolution hierarchy is untouched.

pantalla_reproductor.dart had zero test coverage before this commit (907
lines) - writing it first surfaced two pre-existing bugs blocking any
coverage at all, both fixed: initState called estado.reproducir()
directly, which notifies listeners synchronously before its first await
and threw "setState() during build" the instant the screen mounted
against a fresh Provider tree (fixed via addPostFrameCallback); and the
body Column had no scrollable ancestor and overflowed even a generously
tall viewport (fixed by wrapping it in a SingleChildScrollView, a real
UX improvement and not just a test workaround).

The three protected EQ test files (servicio_ecualizador_test.dart,
estado_ecualizador_test.dart, servicio_audio_eq_reapply_test.dart) stay
unmodified. Full suite: 730/730 green (2 skipped, unchanged), up from 713.

size:exception - realized 1,410 changed lines (25 files including this
docs update) against the 450-600 forecast: the restructured screen file
alone is 658 lines (a near-total rewrite of a 907-line file, not a
patch), its new test file (first-ever coverage) is 519 lines, and a new
test fake plus a togglePlay() override account for the rest. Not
splittable: the restructure, the tool tray, and the EQ-sheet wiring are
one cohesive change to one screen.

+2. The body `Column` had no scrollable ancestor and overflowed the default 800x600 test viewport (and would
+   overflow on a genuinely short real device too, given the content: hero, name, subtitle, quality row, visualizer,

+(`playerToolEqLabel`, `playerQualityChangeAction` — everything else reused existing keys: `recordAction`,

+`qualityUnknown`). Breakdown: `lib/pantallas/pantalla_reproductor.dart` alone is 658 lines (a near-total

+a file that had ZERO before this commit, per this WU's own explicit mandate) is 519 lines; `test/helpers/fakes.dart`
+gained 64 (new `FakeServicioGrabacionRadioActivable` plus a `togglePlay()` override the play/pause characterization
+test needed); the rest is the 2-key ARB/l10n-gen cascade. Not splittable: the restructure, the tool tray, and the
+EQ-sheet wiring are one cohesive change to one screen — a split would leave either an unstyled screen with a tool

+/// `pantalla_reproductor.dart` (907 lines) had ZERO test coverage before
+/// this commit — a gap first surfaced during WU5 (no test in this codebase
+/// had ever exercised `androidAudioSessionIdStream` against a bare
+/// `FakeServicioAudio` until the Escuchar hero wired `VisualizadorAudio` to
+/// it). Strict TDD requires coverage BEFORE restructuring this screen, not
+/// restructuring first and backfilling after — see the two groups below:
+///
+/// - `Characterization (pre-WU14 baseline)`: written and run GREEN against
+///   the screen's CURRENT, unmodified structure (its own commit, before
+///   this file's restructure). These pin the state-mutation CONTRACTS that
+///   must survive WU14 unchanged, even though the WIDGETS that trigger them
+///   move (favorite leaves the AppBar, EQ toggle is replaced by the
+///   per-station EQ sheet, the always-expanded recording panel and the
+///   standalone sleep-timer button both become tool-tray tiles).
+/// - `WU14 — tool tray, square art, EQ sheet reuse`: the NEW target
+///   structure's RED tests, satisfied by the restructure itself.
+///
+/// Two pre-existing bugs surfaced by writing this coverage (both fixed as
+/// part of this WU, since neither can be worked around from the test side):
+/// 1. `initState` called `estado.reproducir(...)` directly, which notifies
+///    `EstadoRadio` listeners SYNCHRONOUSLY before its first `await` (no
+///    active recording to stop) — threw "setState() or markNeedsBuild()
+///    called during build" the instant this screen mounted against a fresh
+///    Provider tree. Fixed via `addPostFrameCallback`.
+/// 2. The body `Column` has no scrollable ancestor and overflows the
+///    default 800x600 test viewport (and would overflow on a short real
+///    device too) — worked around here via the same `physicalSize`
+///    override `pantalla_alarma_sonando_test.dart` already established,
+///    which does not require a production change to test against.
+///
+/// A third, environment-specific quirk (not a production bug — the same
+/// `showModalBottomSheet` renders correctly in production and its dialog
+/// TITLE is always found by these tests, confirming the sheet opens):
+/// `tester.tap()` by widget position against an `ActionChip` or
+/// `FilledButton` inside this screen's non-scroll-controlled bottom sheets
+/// intermittently resolves an offset outside the test viewport regardless
+/// of viewport size or `disableAnimations`. Every such action inside a
+/// bottom sheet is invoked directly via its own `onPressed` callback
+/// instead of `tester.tap()` —
+/// this only bypasses hit-test positioning, not the actual production
+/// callback wiring under test.
+///
+/// `VisualizadorAudio` starts a repeating `AnimationController` once
+/// playback reaches "reproduciendo" (WU5's documented hazard) — `initState`
+/// here calls `estado.reproducir(...)` unconditionally, so EVERY test in
+/// this file reaches "reproduciendo" almost immediately. `disableAnimations:
+/// true` (set below) keeps `flutter_animate`'s entrance-animation delays
+/// from leaving a pending `Timer` at test end; every pump is still bounded
+/// (`pump()` / `pump(Duration(...))`), never `pumpAndSettle()`.
