- ReticleButton: fixed-at-screen-center "+" circle (HTML prototype:
#centerCluster/#reticleBtn), tapping it drops a waypoint at the current
map center.
- CurrentMissionNotifier (Riverpod): holds the waypoint list for the
mission being edited. Reactive single-value state per doc 4.16, so
Riverpod rather than a new Bloc/Cubit.
- MissionMap now renders each waypoint as a CircleLayer marker (white
border, dark fill, matching the prototype's L.circleMarker styling).
- PlanScreen owns the MapController needed to read the camera center on
tap, and wires the reticle to the provider.
Default altitude/speed/catch-radius (60m / 15 m/s / 60m) are hardcoded to
the T1 Ranger default profile values from the prototype for now - TODO
once drone profile settings (doc 3.5) exist.
Verified with flutter analyze, flutter test (incl. a new test covering the
add-waypoint path), and a real run on the Pixel_10a emulator: panned the
map and dropped two waypoints, both markers stayed correctly georeferenced.
