fix: add logo_annotation.server_type field

[raphael0202]

This is the same as ImageModel.server_type, but we store it here to avoid performing a double join with ImageModel table when we need to filter logos by server_type
(LogoAnnotation > ImagePrediction > ImageModel)

First step to resolve #1386
