Currently, `RecipeRunStats` uses the default configuration for the timer's distribution statistic configuration, which uses an expiry of 1 minute and a buffer length of 3. This means that the 99-percentile reported by `RecipeRunStats` will in fact only be computed by the values recorded during the last minute of the recipe run. This commit addresses this by setting the expiry to 24 hours and also only using a buffer length of 1 (translating to one bucket in `TimeWindowPercentileHistogram`), so that there isn't any bias for recent scans/edits.
RecipeRunStats should cover the entire recipe runRecipeRunStats 99-percentile value should be cumulative

I would prefer we simply remove these columns. The only operational use of P99 is in A/B testing and we haven’t ever operated something like that for multiple versions of recipes

These weren't used anyway and the columns are about to get dropped from OpenRewrite: openrewrite/rewrite#6072
