fix(webapp): read the queue ranking from the queue-metrics ClickHouse client

The Queues list ranking still read through the shared query pool, so on a
deployment that puts queue metrics on their own service the ranking query
would hit a service without those tables, get swallowed by the fallback,
and silently sort by name instead of by activity.

Also gives the queue-metrics reader URL a defined fallback, since the
query URL is optional.
