Add terrain/elevation data fetching (Doku 3.9)
Rundet das Altitude-Tab um ein reales Gelaendeprofil ab, damit sichtbar wird, ob die geplante Flughoehe ausreichend Bodenabstand haelt: - domain/mission/terrain_math.dart: reine Sampling-/Geometrie-Funktionen (routeKeyForTerrain fuer Caching, distanzbasiertes Sampling alle 30m, lineare Sollhoehen-Interpolation, terrainDangerRanges fuer Abschnitte mit < 10m Bodenabstand) - unabhaengig testbar ohne Netzwerk/UI. - services/terrain/terrain_service.dart: laedt AWS-Terrarium-PNG-Kacheln (elevation-tiles-prod, zoom 13) und dekodiert sie ueber dart:ui (instantiateImageCodec/toByteData), ohne zusaetzliches Bildpaket. Elevation = R*256 + G + B/256 - 32768 pro Pixel; Kacheln werden pro Route nur einmal geladen (nach Kachel gruppierte Sample-Punkte). - ui/providers/terrain_provider.dart: cached das geladene Profil ueber routeKeyForTerrain - reine Werteaenderungen (Hoehe/Speed) loesen keinen erneuten Kachel-Download aus, nur eine tatsaechliche Ortsverschiebung. - ui/widgets/full_value_chart.dart: _paintDangerBands/_paintTerrain zeichnen rote Gefahrenbaender bzw. die braune Gelaende-Flaeche, in der gleichen Reihenfolge wie im HTML-Demonstrator (dangerHtml, grid, terrainHtml, dann Soll-Kurve obenauf). - ui/widgets/waypoint_list_panel.dart: triggert ensureFor() beim Wechsel auf den Altitude-Tab sowie bei Routenaenderungen waehrend dieser aktiv ist (ref.listenManual auf currentMissionProvider). Getestet: 13 neue Unit-Tests fuer die reine Geometrie/Sampling-Logik, 3 Service-Tests mit einer zur Testzeit synthetisch erzeugten PNG (dart:ui-Encoding, keine Testasset-Datei noetig). Alle 80 Tests sowie flutter analyze bestehen. Manuell auf dem Pixel_10a-Emulator verifiziert: Altitude-Tab zeigt das reale Amsterdam-Gelaendeprofil (nahe Meereshoehe) korrekt als Flaeche unter der Sollhoehen-Linie.
