Explore the statistics: a query log to drill down by client, name, view and more; storage on the dashboard

jarld keeps every answer for a while (stats.retention.queries, default 7 days) in the statistics database: time, client, view, name, type, result and what blocked it. Every client, name, view, record type, result and blocklist on the Statistics page leads to an explore page for it: answers over time, the top values of every other dimension (each a link that narrows further) and the latest answers. GET /stats/explore.

The dashboard shows the size of Jarl's databases (and the query log's rows) and, per disk Jarl uses, how full it is and the databases' share.
