feat: HTMX-ify article publish/delete actions for inline updates

- Publish/Unpublish returns updated <tr> partial via HTMX
- Delete returns empty string to remove row without page reload
- Extract article_row.html partial (used by both results table and
  individual HTMX responses)
- article_results.html now includes article_row.html via loop
