fix(map): disable vertical map repetition — eliminate spurious vertical artifact lines

osmdroid's vertical (Y) map repetition wraps points below the viewport up to
the top edge. Antarctica's full-circle ring then draws a full-height artifact
line whenever its X range crosses the screen at low zoom. The map must never
repeat vertically, so disable setVerticalMapRepetitionEnabled.
