web-player: cards and grids (MediaCard)

MediaCard now builds its own art (src/trackIds via Artwork
size="fill", or a custom art snippet) and its own play button
(onPlay, with a scrim and a glass PlayButton on hover) instead of
relying on each wrapper passing it a snippet. Replaces AlbumCard,
PlaylistCard and MixTile, which are removed along with
MediaGrid.svelte (their grids move to the
grid-cards/grid-cards-lg/grid-tiles/grid-wide @utility recipes).

format.ts gains albumMeta() and playlistMeta() (previously ad-hoc
calculations inside each card). Explore's genre tile moves from an
inline style= gradient to the genre-tile @utility recipe +
--tile-hue. Along the way, fixes the "follower/s" pluralization on
the user profile that had been missed.

Delta documented: the art's hover-zoom and the scrim+PlayButton
(previously exclusive to MixTile) become MediaCard behavior gated on
the onPlay prop — they'll apply to any future card that uses it, for
consistency.

Verified with npm run check/build; no authenticated visual QA (Docker
unavailable this session).
