feat: suppression individuelle de logs + trace obligatoire des suppressions

src/Controller/Admin/LogsController.php:
- purge(): compte les logs avant suppression, supprime tous les logs,
  puis cree un nouveau log via logDirect() avec le message
  "Suppression de tous les logs (X entrees supprimees)" pour garder
  une trace de la purge meme apres suppression
- delete(): nouvelle route POST /admin/logs/{id}/delete, supprime un
  log individuel puis cree un log de trace avec le message
  "Suppression du log #X (action du date)" pour conserver l'historique

src/Service/AppLoggerService.php:
- logDirect(): nouvelle methode qui cree un AppLog avec une action
  personnalisee sans passer par le dictionnaire ROUTE_LABELS
  (utilisee pour les traces de suppression)

templates/admin/logs/index.html.twig:
- Bouton supprimer (croix rouge) ajoute a cote du bouton PDF
  sur chaque ligne du tableau, avec confirmation data-confirm
