fix(buscar): filter pills, Idioma chip, results eyebrow, states screen

Audit 6.2 (t4:292-293): active filter pills are brand-teal tinted with a 15px close glyph and radius 10 -- was Material's own Chip theming. Audit 6.3 (t4:294-295): an "Idioma" entry chip is now always reachable once a search is active -- there was no standalone entry point for language filtering before (only bundled inside "Filtros"). Opens the same existing filter sheet rather than a new idioma-only picker. Audit 6.4 (t4:299): the results-count line now uses eyebrowLabel styling -- was labelLarge (14/w800). Audit 13.3/13.4 (t4:649-651): the search-results loading skeleton gains the missing "BUSCANDO EMISORAS..." eyebrow, and its row gap is now 4px, not 10. Audit 13.5/13.6 (t4:657-668): a new purpose-built _TarjetaSinResultados replaces PluriEmptyState ONLY in the search-no-results branch (that shared widget is left untouched for its other unrelated call sites -- favorites empty state, the discovery grid). The title now quotes the typed query ("Sin resultados para <<jazzz>>"), and the clear-filters pill sits INSIDE the card. New ARB key searchNoResultsForQueryTitle. Item 6.1 (compact 60px active-search header replacing the persistent glass pill) is NOT implemented: existing tests confirmed the quality (bitrate) filter has NO entry point anywhere in the app besides the header's "Filtros" pill (added first via _abrirYSeleccionarCalidad while a country filter is ALREADY active, i.e. mid active-search). Hiding PluriRootHeader during active search would make quality filtering unreachable -- a real capability regression the task's own "presentation changes, capability does not" principle forbids. Re-plumbing where that filter lives is a bigger change than this visual-fidelity pass should make unilaterally.
