Fixed issue where dragged bars weren't updating visually because a single
barRef was shared across all bars. Now each bar passes its element reference
to the drag handlers, allowing proper width calculations during drag.
Changes:
- Renamed barRef to activeBarRef for clarity
- Updated handleMouseDown/handleTouchStart to accept bar element parameter
- Pass e.currentTarget as bar element in onMouseDown/onTouchStart handlers
- Clear activeBarRef on drag end (mouseup/touchend)
This fixes the visual feedback - bars now correctly resize as you drag them.
