feat: say which checks use the two periods and which use all the data

'Aug 2 – Sep 13 compared with Jun 7 – Aug 1' reads as if the review ignored
everything older. Rates are windowed; appeal deadlines, payer speed, overturn
rates and the finance reconcile are not — the coverage block now says so and
names the full span of the table.
