fix: Correct MultiPolygon coordinate flattening for fitBounds

Browse source 
MultiPolygon coordinates need .flat(2) not .flat(1) to get actual
coordinate pairs. With flat(1), we were iterating over rings instead
of coordinates, causing invalid lat values > 90.

Also added bounds validation before fitBounds to catch future issues.
