Sorting support for model and user list endpoints

Model and user list endpoints now support sorting via sort_by and sort_direction query parameters.

Models

GET /models, GET /models/{owner}, and GET /user/models can be sorted by created_at (default) or predictions_count. When sorting by prediction count, only models with at least one prediction are returned.
