#2256 Fix for webpage - about - model settings -save

Description

@Niko1221  I’m running Strata in a Docker container on my Unraid server, and I noticed that the Save button on the model settings page isn’t saving changes to my volume-mapped folder:
...
volumes:
      - /mnt/cache/system/compose/strata-test/strata-data:/data
...

Here is a patch that fixes this:
