Move DQV label check into public alert criterion

Previously, the data quality check was re-run by the Orchestrator
whenever an event was added to a superevent. Depending on the
result, the superevent would have been updated. This feedback
between the Orchestrator and the Superevent Manager was race-prone.

Now, the Superevent Manager is responsible for running data quality
checks whenever an event is ingested, and the data quality status
is included in both the public alert condition and the preferred
event sorting key.
