Local convenience wrapper for the temporary session backfill.
Production/runtime callers should invoke
GoodAnalytics.Core.Sessions.Backfill.run/1 from compiled application code,
a release, or a remote console. Mix is local-only and is not required by the
runtime backfill API.
This task is temporary maintenance code intended to be removed in a later cleanup after deployed environments have run the session backfill.
