feat(now-playing): redesign page as info dashboard (#266)

Replace the flat Now Playing page with a two-column dashboard: hero (cover, metadata, badges, Last.fm stats + love button, release-age tagline), and a grid of themed cards (Album tracklist with sliding window, most-played-by-artist, credits, about-the-artist with Last.fm bio fallback, compact discography contact-sheet with expand, upcoming tours via Bandsintown). Adds lastfmGetTrackInfo + lastfmGetArtistStats for global listener counts + userplaycount, plus Last.fm love/unlove wired to the new hero button. Module-level TTL caches per entity keep same-artist track switches instant. Artist-image guard filters the well-known Last.fm no-image placeholder so the card collapses cleanly when no real image exists.
