feat(admin): live-poll Articles and Scenarios tabs during generation

- Add _is_generating() helper — queries tasks table for pending generate_articles tasks
- Pass is_generating to article_results partial (both full page and HTMX route)
- article_results.html: render invisible hx-trigger="every 3s" div when generating;
  polling stops naturally once generation completes and div is absent
- Add /admin/scenarios/results HTMX partial route with same is_generating logic
- Extract scenario table into admin/partials/scenario_results.html partial
- scenarios.html: wrap table in #scenario-results div, include partial
