feat(plot): add smoothed extrema line to min_max subplot with weighted smoothing

- Add 'smoothed-extrema' column displaying weighted extrema after smoothing
- Position smoothed extrema line below maxima/minima bars in plot z-order
- Use 'wheat' color for better visual distinction from red/green bars
- Store smoothed result in variable before assigning to both EXTREMA_COLUMN and smoothed-extrema
