fix(music): unstick arrows and number placement at the playlist top

The playlist header is a multi-line overlay string anchored at buffer position 1. With point on the top row, next-line's visual motion stepped through the header's screen lines. Those all map back to position 1, so arrows never moved point. The buffer now moves by logical lines (each row is one), which skips the header display entirely.

The same shared anchor put row 1's number above the header instead of beside its track: both overlay strings sit at position 1 and the number rendered first. Number overlays now outrank the header's priority, so the number lands next to its own row.
