Subject: [PATCH] feat: switch to NA tileset + browser geolocation

Swap tile source from idaho.pmtiles (427 MB, Idaho-only) to na.pmtiles
(31 GB, CONUS + Canada + Mexico + Alaska). Replace MapLibre GeolocateControl
with browser geolocation API that flies to user location on load and stores
coordinates in Zustand for future use.
