feat(music): move single to 1, save to s, drop the stop key

In the playlist buffer, single-track mode moves off s onto 1 and save moves off v onto s. The stop key (S) is gone, since SPC/pause already covers stopping. The Mode/Keys header legend follows, and v is now unbound. Stop is still reachable from the global music prefix (C-; m s).
