feat(energy): hydrogen daily — period bar chart with anomaly coloring

Mirrors the electric-view treatment: a 时段每日加氢量 bar chart sits
between the customer toggle and the table. Bars use the cyan→blue
gradient by default; days where |chainPct| >= 30% render in solid
emerald (positive) or red (negative), giving an at-a-glance view of
anomalous days that's reinforced by the table's row tinting below.
