trim mobile labels in journey picker + guard JourneyMap flyTo

- mobile-shorten 'Alle Fotos' → 'Alle' in MemoriesPanel picker and the
  Journey ProviderPicker filter tabs (four tabs no longer wrap)
- mobile-shorten 'Datum wählen' → 'Datum' in the entry-editor DatePicker
  placeholder
- guard JourneyMap.tsx flyTo: getZoom() throws "Set map center and zoom
  first" when activeMarkerId arrives before fitBounds has set a view —
  wrap in try/catch and fall back to setView.
