fix(geoportal): simplify building labels — show full cadastral_ref

Browse Source 
Previous index-of/slice expression wasn't rendering. Simplified to
just show the full cadastral_ref (e.g. "77102-C1") as-is. MapLibre
auto-hides overlapping labels. This is a diagnostic step to verify
the tile property is accessible.
