feat: Add benchmark chart toggles for y-axis starting at 0.0, outlier clipping

[RobertJacobsonCDC]

Added two quality of life toggles to the benchmark history page:

1. start the y-axis at 0.0, making absolute benchmark scale easier to compare across runs. Turning it off preserves Chart.js’s existing automatic axis behavior.
2. MAD clipping heuristic for extreme high outliers in time-series charts.

Both are toggled on by default.
