fix aggregate cost charts: per-metric ranges + marked means

eval.py bins costs 0-1000 (width 10); lataccel is ~0-5 so all 5k segments collapse into one bar. Re-binned per metric, zoomed to the 98th pct, with karti-vs-pid overlay and mean lines.

 ## How it works

 Feedforward does the driving. PID just trims the residual.
