#5355 "Traefik page doesn't load": /plugins/traefik/rows took 12-28 s.
It ran a query per router ever seen, and each raw row in the range was a
heap fetch. traefik_004 rebuilds the router index to cover the charted
columns and indexes scraped_at for the request chart; router_history reads
the current routers' buckets in one query.
