The flag-media-questions CLI command only caught questions that
existed in the DB when it ran once. Any question created, imported,
or edited afterward could add media without ever being flagged for
review, since nothing gated new writes going forward. CreateAsync,
UpdateAsync, and UpsertManyByExternalIdAsync now all run new/updated
questions through ApplyMediaReviewGate, which flags any question that
has media and isn't already flagged.
