When moving posts to a new topic fails (e.g. title too short, missing required t…ags, duplicate title), the modal only shows a generic "There was an error moving posts." message. Users had to open browser dev tools and inspect the network response to find the actual reason for the failure.
Use `extractError` from `ajax-error.js` to extract the specific error message from the server's JSON response, falling back to the generic message when no details are available.
