Permanently deletes a segment configuration. This cannot be undone.

Deleting a config does not fail the runs that reference it — it silently stops segmenting them. Run Segmentation skips a configId that matches no existing config, so a run that still names a deleted config returns 200 with that dimension simply absent from the results; only a run whose configIds match nothing at all returns 400. Remove the id from your callers when you delete the config, and do not rely on an error to tell you.

Returns 204 with no body on success. Returns 404 if no config has the given configId.
