fix: GeometryCollection incompatible avec colonne MultiPolygon

Browse Source 
ST_Collect peut retourner une GeometryCollection selon les sous-types.
Correction : ST_CollectionExtract(..., 3) extrait uniquement les polygones,
ST_Multi garantit le type MultiPolygon, ST_GeomFromText fournit un fallback
vide typé correctement.
