Instead of modeling remote WebDAV servers as actual webdav.FS instances, we now just proxy traffic to them. This not only simplifies the code, but it also allows WebDAV locking to work correctly by making sure locks are handled by the servers that need to (i.e. the ones actually serving the files).
