fix(enrichments): address second-pass PR review

- updateWorkflowGroup output diff now keys on outputId (falling back to
  blockId::path) so enrichment outputs — which share empty blockId/path —
  no longer collapse to one key and drop sibling columns.
- Enrichment terminal write now clears output columns absent from the result,
  so a partial/empty re-run doesn't leave stale values.
- Editing a group whose enrichment was removed from the registry shows an
  explanatory panel instead of silently falling through to the new-enrichment
  catalog.
