fix(geoportal): use w-full h-full on map container (MapLibre overrides position to relative)

MapLibre sets position:relative on its container element, which overrides
our absolute inset-0 and causes height to collapse to 0. Using w-full h-full
instead works because the parent (absolute inset-0) has a definite computed
height from positioning.
