show_temp_plot: scale physical timeline by M73 trapezoid estimate

Browse Source 
Physical dist/speed ignores acceleration/deceleration, giving
underestimated total time (29 min vs real 48 min). M73 from the
trapezoid planner accounts for accel/decel and is closer to reality.

Now we keep physical DISTRIBUTION (proportions per-filament) but
scale the X-axis so total time matches M73 trapezoid estimate.
