test(user) : couvre le soft-delete + désarchivage admin et corrige les retours de review

- ajoute des tests fonctionnels (archive au DELETE, exclusion de la
  collection, listing/désarchivage admin, anti-auto-archivage) et un test
  unitaire du ArchivedUserChecker
- expose un filtre BooleanFilter `archived` + bypass admin dans
  ExcludeArchivedUserExtension pour lister les archivés (?archived=true)
- rend `archived` modifiable par un admin (groupe user:write + ApiProperty
  ROLE_ADMIN) → désarchivage possible via PATCH /api/users/{id}
- RestoreMissingUsersCommand : ne compte que les insertions réelles
  (ON CONFLICT DO NOTHING n'est plus comptabilisé à tort)
- relève memory_limit des tests à 512M (boot sérialiseur API Platform)
