fix(ui): ArrangementDialog drag whole box, persist changes across switch, hover highlight

- Remove drag handle restriction — entire pill box is now draggable
- Keep local copy of arrangements so edits survive switching between
  arrangements (was reading stale props after switch-back)
- Highlight corresponding left pill when hovering right lyric preview
