fix(web): center NowPlaying star vertically with the whole track-info block

The favorite star lived inside .np-title-row, so it sat pinned to the title line
rather than centered against the title + album + artist block. Move it out to be a
flex sibling of .np-text inside .np-info (align-items:center), so it centers on the
full text block. Bump SW cache to ns-v43.
