- Lock orientation to landscape (sensorLandscape in the manifest,
SystemChrome.setPreferredOrientations in main.dart) and enable immersive
fullscreen, matching the prototype's full-bleed map UI (doc 7.7).
- Add MissionMap widget: flutter_map + standard OSM raster tiles, same
default center/zoom as the HTML prototype (Amsterdam, zoom 16), OSM
attribution bottom-left. PlanScreen now renders it full-screen instead of
the placeholder text.
- Add the release-manifest INTERNET permission (previously only present in
the debug manifest, which would have silently broken tile loading and any
future network calls in release builds).
- Update the smoke test to check for the FlutterMap widget instead of the
removed placeholder text.
Verified with flutter analyze, flutter test, and a real run on the
Pixel_10a emulator (fullscreen landscape confirmed, tiles loading).
