Read-only: opens CATALOG, the Account DB of every active tenant listed there and the blob
container, with a 10 s timeout each. On the Account DBs it also reads whether the
login may UPDATE dbo.Report, which the pipeline needs to complete a report. It also opens the
reporting database (PostgreSQL, ConnectionStrings:HypnusReporting — used by Hypnus.Viewer, not
by this app) and lists the devices in it.
