1. Article age filter (ingestion.py + config.py):
- New setting pipeline_max_article_age_days=7 (0 = no limit)
- Skip RSS entries older than N days before expensive extract_article()
- Prevents old articles from Google Alerts re-entering pipeline
2. Image URL pre-validation (ingestion.py):
- HEAD request probe for each primary image candidate during ingestion
- Falls back to next-best candidate if primary returns 4xx
- Network errors treated as OK to avoid false negatives on flaky servers
3. Stale WP draft cleanup (pipeline.py):
- Quality gate rejections now delete any pre-existing WP draft (wp_post_id)
- Prevents orphaned drafts when re-running articles that previously had drafts
4. Schedule overview UI (scheduler.py + admin_ui.py + admin_schedule.html):
- New /admin/schedule page showing calendar grid of all booked slots
- Distinguishes Pipeline-DB slots from WordPress-only slots
- Link added to dashboard navigation
5. Retry for failed articles (admin_ui.py + admin_dashboard.html):
- New POST /admin/articles/{id}/retry endpoint: resets to 'new', releases slot
- '🔄 Wiederholen' button shown in dashboard for all 'close' (error) articles
