feat(ui): design token discipline, accessibility and i18n pass

Browse Source 
- Replace all hardcoded Color literals outside lib/tema with theme tokens (new static brand palette in PluriWaveTokens); media notification uses the brand color instead of the Material default purple
- Favorite button on station cards grows to a 48dp target and becomes an independent semantics node for screen readers (Semantics container fix)
- All flutter_animate call sites route through the PluriAnimate reduced-motion gate (zero direct .animate() left)
- Locale-aware short dates via intl DateFormat (new lib/l10n/formato_fechas.dart) replacing the hardcoded DD/MM/YYYY; proper plural messages for the favorites counter; example stream URL as a localized key - all 13 locales
- Rounded shimmer placeholders matching card radii; shimmer loading state in search instead of a bare spinner; rounded icon variants unified in settings; bottom-sheet conventions on the custom station form
- Fix latent debug crash: vacation editor read AppLocalizations in initState
- 11 new tests (121 total green), flutter analyze clean

## Deviations from design (Batch 7)
1. **`Semantics(container: true)` on the favorite button (not in task text).** The task only asked for `Semantics(button, label)` — which ALREADY existed. The RED test proved the real defect: the card-level InkWell merged the favorite into a single semantics node, so screen readers could not reach the action. `container: true` forces an own node; this is the actual S5-R2 fix.
2. **`fechaCortaLocalizada` lives in NEW `lib/l10n/formato_fechas.dart`** (task said edit `_fechaCorta` in place). The private top-level function is untestable from `flutter test`; the public helper takes a locale tag (testable without widgets) and `_fechaCorta(l10n, fecha)` delegates via `l10n.localeName`. Spec scenario S5-R4-A is met verbatim.
3. **Brand token is `PluriWaveTokens.brand`, not `brandColor`** (task text guessed the name). Defined as a `static const` so it works in the `const AudioServiceConfig` context; `electricMagenta` now references it (single source for 0xFF21D4D9). `brightCyan`/`auroraTeal`/`skyBlue` added the same way for palette colors that had no token.
4. **`Colors.white` overlays mapped to `colorScheme.onSurface`/`onPrimary` and `tokens.glassBorder`** — the scheme's `onSurface` is 0xFFF2F7FA (near-white), so visuals are intentionally near-identical while becoming theme-driven.
5. **`pluriScaleIn` on the hero adds a fade** the old bare `.scale()` did not have (the shared helper pairs fade+scale). Visually negligible at 420 ms; keeping one canonical scale-entry beats a third helper.
6. **Icon variants: only base-name icons got `_rounded`** (9 sites). The `*_outlined` Material family (folder_outlined, backup_outlined, upload/download_outlined, verified_outlined, music_note_outlined) has NO rounded-outline variant; switching them to filled `_rounded` would change their visual weight, so they stay outlined.
7. **`streamUrlHint` added as an l10n key** (the prompt's "handled per design"): the hardcoded hint leaked a Spanish-looking host (`stream.ejemplo.com`) into all 13 locales; the key ships the same neutral `stream.example.com` URL everywhere but is now localizable.
8. **`_EditorVacacionesSheet` initState l10n crash fixed** (flagged in Batch 2 as a latent debug-mode crash, explicitly brought into this batch's scope): controller now created lazily in `didChangeDependencies`, mirroring the alarm-editor fix.
9. **Pagination spinner in PantallaBuscar kept** — S5-R6 covers the initial loading state (explore C11, lines 241-245); the small inline load-more spinner is a different affordance and was left untouched.
10. **`flagsCollection`/`Tristate` instead of `SemanticsFlag.hasFlag`** in the a11y test — `hasFlag` is deprecated in the current SDK and `flutter analyze` flags it; also `tester.ensureSemantics()` must be disposed in the test body (an `addTearDown` runs after the framework's handle-leak check).

@@ -495,9 +574,28 @@ From tasks.md Section 11 — S1 items still pending from Batch 1, plus new S2 it
4. **Scoped rebuilds (S4-R5):** while audio plays/buffers, home/favorites/settings should feel identical (no visual change expected — the win is fewer rebuilds); list reordering in Ajustes still re-sorts home, search results and favorites.
5. **Stop recording on pause/stop/station switch:** unchanged orchestration in EstadoRadio — verify recording stops when playback pauses/stops or station changes.
## Verification summary (Batch 7)
- `flutter test`: 121/121 passing (110 baseline + 11 new across 6 files); re-run after `dart format`
- `flutter analyze`: No issues found (identical to baseline); re-run after format
- `dart format`: applied to all 20 touched Dart files (7 reflowed); gen/ untouched by hand
- `flutter gen-l10n`: run once after the 13 .arb edits
- Color-literal audit: `rg 'Color(0x' lib` excluding `lib/tema/` and `lib/l10n/gen/` → **0 matches** (was 14)
- `rg '.animate()' lib` → 0 direct flutter_animate call sites (all via PluriAnimate)
- `flutter build`: NOT run (forbidden)
- No Kotlin/native files touched in this batch
### Manual verification items added by Batch 7 (user)
1. **Visual parity sweep (S5-R1):** home/buscar/favoritos/ajustes/alarmas/reproductor look unchanged — token mapping was value-preserving (onSurface ≈ white; electricMagenta = brand). The settings "check" icons are now mint (`colorScheme.secondary`) instead of Material green — intentional.
2. **TalkBack (S5-R2):** on a station card, the favorite toggle is now reachable as its OWN button ("Añadir a favoritos / Quitar de favoritos") separate from the card; alarm/vacation images announce their labels.
3. **Reduced motion (S5-R3):** with "remove animations" enabled, home grid/search results/player screens render instantly with no entry animations.
4. **Locale dates (S5-R4):** switch app language to English → alarm editor and vacation ranges show M/D/Y order; Japanese shows Y/M/D.
5. **Media notification (S5-R8):** the playback notification accent is teal (brand), not purple, on devices that honor `notificationColor`.
