refactor(hanzo): lead the globe with the honest native points layer, arcs off by default

The trafficArcs feed carries a demo fallback (demoTraffic), so enabling it by
default on the flagship could paint fabricated flows when native data is absent. The
new native `traffic` points layer is ALWAYS honest (empty until real traffic lands,
never demo), so the hanzo default now leads with it and ships trafficArcs OFF — still
one toggle away for the animated flow lines (which are native-sourced once live).
