Fails the run of a migration job Oban discarded — its last attempt timed out or crashed past every rescue, so AshOban never ran the trigger's on_error — with Oban's reason (MishkaCmsMigration.MigrationRun's :fail), which an admin can Run again. It runs outside any job, so it acts as the system (authorize?: false), and hands :fail the job as AshOban hands it its trigger's on_error (context.ash_oban.job), so what the run's steps tell says which step failed (MishkaCmsMigration.Resources.Notifiers.Steps). A run no longer dry running or importing is left as it is. Attached to Oban's [:oban, :job, :exception] telemetry by MishkaCmsMigration.Workers.attach/0.

A handler that raises is detached by :telemetry for good, so a failure here is logged and the handler stays attached.
