GPX-Import via Teilen-Menü und 'Öffnen mit'

Andere Apps können jetzt GPX-Tracks zu Ban Yaro Go schicken (Komoot,
Outdooractive, GPSies, AllTrails, Files-App, Mail-Anhänge, AirDrop).

- Info.plist:
  - UTImportedTypeDeclarations: com.topografix.gpx (conforms to
    public.xml/data/content, ext gpx, MIME application/gpx+xml)
  - CFBundleDocumentTypes registriert die UTI als Viewer (LSHandlerRank
    Alternate, damit wir nicht die Default-App werden)
  - LSSupportsOpeningDocumentsInPlace=true
- Support/GPXParser.swift: schlanker XMLParser/SAX-Reader für
  <trkpt>/<wpt>/<rtept>, Track-Name aus <trk><name>, ele + ISO8601 time
- Views/GPXImportSheet.swift: Sheet mit Map(MapPolyline)+Start/Ziel-Pins,
  Distanz/Punkte/Dauer-Karte, zwei Aktionen:
    1. 'Als Tour übernehmen' — Name editierbar, Hunde-Picker (FlowDogs),
       öffentlich-Toggle → POST /api/routes
    2. 'Nur ansehen' — Startpunkt in Apple Maps
- BanYaroGoApp.swift: .onOpenURL prüft .gpx, security-scoped resource,
  parst und triggert das Sheet via TrackBox-Wrapper
