Skeleton SAM Follow Up: Allow predictions in low resolutions

[MichaelBuessemeyer]

Detailed Description

There is currently a PR to enable SAM Quick Select via Skeletons. The prediction is always done in the best resolution. However, a user might desire the prediction to be done in a higher resolution. Therefore, e.g. a dropdown or other kind of setting could be added to the modal for the user to select the resolution in which the prediction using SAM should be done.

For this to work, the prediction saga also needs to be adjusted as it currently only supports mag 1 predictions. Maybe even the backend route loading the embedding needs to be adjusted.
