web-player: P7 — filas (ListRow, MediaIdentity, EqBars)

Crea MediaIdentity.svelte (renombra y generaliza TrackTitleCell,
puramente presentacional: arte + título + subtítulo, sin manejo de
click) y ListRow.svelte encima (href|onclick, active, size xs/sm/lg,
variant row|card, leading/trailing/overlay). Usa MediaIdentity también
en player/TrackInfo... (pendiente: TrackInfo se deja para P12, que ya
tiene tarea explícita de tocar ese archivo).

Migra a ListRow: SearchResultRow (Explorar, 4 grupos — se borra el
componente), Inicio (Continuar escuchando, Populares, spotlight, Tus
playlists), Queue (A continuación), Sidebar (playlists). Las 6 tablas
de pista (AlbumTrackTable, PlaylistTrackTable, library, liked, mixes,
LibraryPicker) migran a MediaIdentity con su propio use:pressable
local, ya que TrackList (P8) todavía no existe.

EqBars gana prop `overlay` (fondo scrim/45, color on-art) que
sustituye a NowPlaying.svelte (borrado). Corrige de paso 6 llamadas a
plural() que P5 había dejado sin migrar (liked, library, mixes,
playlists, PlaylistHeader, Inicio).

Deltas documentados en el registro del plan: fila activa de Sidebar
ahora usa el tinte de acento (antes gris neutro); tarjeta "Tus
playlists" de Inicio pierde la línea de autor redundante y su radio
pasa a rounded-art; filas de Queue pierden el opacity-80 del arte.

Verificado con npm run check/build; sin QA visual autenticada (Docker
no disponible en esta sesión).
