Review queries were issued without a severity filter, so the thumbnail
bar, gallery and timeline showed every Frigate review item -- alerts and
detections alike -- regardless of what a camera is configured to alert
on. Severity could only be narrowed interactively, in the media filter
drawer, and that choice did not persist.
`media.severities` resolves into the default query the same way
`media.reviewed` does, and is overridden by an explicit severity filter
so the media filter drawer keeps working. Unset means all severities, so
existing behaviour is unchanged.
