Adds computeDistanceToHomeM() (mission_stats.dart) alongside the existing rubber-band-target helper, wired through MissionFooterBar -> BottomStatsBar the same way flyMissionStatus already is. Only appears once a home point is known, as the last field after waypoint/distance/ duration. Generalized HomePointIcon to take an optional strokeColor: the map marker keeps its dark-fill-plus-white-outline look, while the details pill uses a plain white fill (strokeColor: null) to match the existing monochrome flag/ruler/clock icons instead of looking like a dropped-in map pin.
