rcourtman e63da80b65 Colour Alert History frequency bars by severity ...

The frequency chart drew every period in one blue under a legend of
coloured severity dots that described nothing in the bars, left info
alerts out of that legend, and used a floored log scale on which a
25-alert burst looked barely three times one alert.

Each period now stacks critical, warning and info in the legend's own
colours, counted with the alerts contract's closed severity vocabulary,
and bars scale by the square root of their share of the busiest period so
a burst stands clear while quiet periods keep a readable mix. The legend
counts all three severities, and the tooltip and accessible name carry
each period's breakdown. Light-theme warnings use amber-700 because
yellow on the chart surface was under 2:1, and a selected period is
ringed instead of dimming the rest below 3:1.

The chart's two test files are registered as alerts frontend proofs.
