[Bug]: categories used to map area exposed analysis results are incorrect

[wadhwamatic]

What happened?

If I run an analysis and choose 'area exposed' as the statistic, the results show the hazard layer's color scale in the legend, but values are based on percentages so there's a mismatch.

This is a byproduct of PR #1297

In this case since we are reporting percentages, we could use a standard classification:

"<20%": #fee5d9
"20 - 39%": #fcae91
"40 - 59%": #fb6a4a
"60 - 79%": #de2d26
">=80%": #a50f15

If there's a short term solution to 'hard code' this, that would work. In the longer term, perhaps we can add a new feature to configure this?
