feat(front) : util httpExternal + autocomplete adresse BAN (ERP-66)

- httpExternal : client dedie aux API publiques externes (URL absolue, sans cookie de session, timeout), seul point d'entree autorise pour un $fetch externe (regle frontend n°4). - useAddressAutocomplete : implementation BAN (api-adresse.data.gouv.fr), recherche ville (type=municipality) et adresse, mapping GeoJSON, throw en cas d'erreur/timeout (mode degrade cote composant). La recherche d'adresse n'impose pas type=housenumber (sinon 0 resultat tant qu'aucun numero n'est saisi) — spec-front mise a jour en consequence. - Tests Vitest : httpExternal, useAddressAutocomplete, et cas limites supplementaires pour formatPhoneFR.
