fix(build): replace deprecated LatLngBounds property accessors

MapLibre 13.0.1 only exposes northEast/southWest LatLng corners; the
flat latSouth/latNorth/lonWest/lonEast properties don't exist and cause
unresolved reference errors. Replace all occurrences in ParticleWindView
and MainActivity with the correct .southWest.latitude / .northEast.*
accessors.
