Title: fix #29406: grace note navigation

Replaces previous PR. Behavior is now that left/right will navigate through all grace notes whether in note input mode or not. If in note input mode, behavior is as before (when it worked): grace notes show as selected, but "blue box" note input cursor remains fixed on main note.
