fix: Admin-Queue-Ansicht — Daten wurden nicht angezeigt

Bug: Template erwartete data.running, data.queued, data.failed.
API liefert aber data.jobs (mit status-Feld pro Job). Daher waren
alle drei Tabellen IMMER leer, selbst bei laufenden Jobs.

Fix:
- jobs nach status filtern (running | queued/pending | completed | failed)
- Neue Sektion "Zuletzt abgeschlossen" — vorher gar nicht angezeigt
  (20 completed Jobs auf dev waren unsichtbar)
- 4. Stat-Kachel "Abgeschlossen (Total)" mit data.processed_total
- Konfig-Info-Zeile: workers_running, max_size, avg_job_duration_seconds,
  estimated_wait_seconds — alles vorher ungenutzt im API-Response
- Spalte "Gestartet" → "Dauer (s)" (Daten-mismatch, started_at gibt's
  im API nicht)
- Wartende Jobs: bundesland-Spalte raus (nicht im API), durch
  Job-ID-Kurzform ersetzt
