Cluster not displayed correctly in metadata panel #167
Description
The image metadata display panel (fileNameBanner) displays a badge with the current image's umap cluster. However, the cluster information is not correct. Instead of showing the current image's cluster, the badge shows whatever cluster was last selected regardless of the current image. This needs to be corrected.
In addition, images that are not clustered are being displaying as cluster=-1. Instead, the badge should read "unclustered" for consistency with the fixed-score display.
