When filtering housings by geo codes (establishment, intercommunalities, localities), if the intersection results in an empty set, return 0 results immediately instead of querying without the geo filter. Previously, an empty localities array would be passed to the query, but since `if (filters.localities?.length)` is falsy for [], the whereIn filter was not applied, returning all housings instead of none. This fixes the issue where perimeters with empty intersection between user geo codes and establishment geo codes would display/count all housings.

Problème
Les filtres et/ou le comptage du parc de logements ne fonctionnaient plus correctement. Quand les périmètres avaient une intersection vide entre les geo codes de l'utilisateur et ceux de l'établissement, tous les logements étaient affichés/comptés au lieu de 0.
Cause
Dans
housingRepository.ts, quand l'intersection des geo codes résultait en un tableau vide[], la condition :était falsy (car
[].length === 0), donc le filtrewhereInn'était pas appliqué et TOUS les logements étaient retournés.Solution
Ajout d'une vérification précoce : si on avait des restrictions géographiques (establishment, intercommunalities ou localities) mais que leur intersection est vide, on retourne immédiatement 0 résultats au lieu d'exécuter une requête sans filtre géographique.
