i18n(ai-workbench): translate ListView via $_() — tabs, filters, audit table, timeline buckets

- Tabs (Timeline / Datenzugriff)
- Filter labels (Modul/Mission/Agent) with shared "alle" option
- Time-range buttons routed via dynamic key labelKey
- Audit: loading, error_prefix interpolation, empty paragraph, 4 column headers
- Timeline empty state
- Bucket revert button (title + Läuft… / Rückgängig label) + event-count tooltip + event-link "Zum Modul"
- Confirm + alert summary parts ({n} zurückgenommen / nicht unterstützt / fehlgeschlagen) + "Revert fehlgeschlagen — siehe Console." fallback
- Date/time formatters switched to get(locale) ?? 'de'

Baselines: hardcoded 1090 → 1082 (8 cleared); missing-keys baseline +1 (ai-workbench.list_view.range_* dynamic key).
