i18n(spiral): translate ListView via $_() — visualization, stats, apps, palette, actions, info-box

- Section titles (Visualisierung/Statistiken/Apps/Farbpalette/Aktionen)
- Viz controls: Zoom + Grid labels, empty-state copy
- Stats grid: Bildgröße/Events/Pixel belegt/Kompression/Aktueller Ring/Apps aktiv labels, Ring {n} value, "Zuletzt gesammelt: …" line
- App cards: empty-state, "{n} Events" trailing text
- Action buttons: Sammle…/Daten sammeln, PNG herunterladen, PNG importieren, Zurücksetzen
- Info-box heading + 4-line body
- Toast/confirm: "Import fehlgeschlagen: {error}" alert + "Alle Spiral-Daten löschen?" confirm

Baselines: hardcoded 1230 → 1218 (12 cleared); missing-keys baseline unchanged.
