Revue complète : sécurité, optimisations et UI/UX mobile

Sécurité
- JWT : un JWT_SECRET d'exemple ou trop court est ignoré au profit d'un
  secret aléatoire conservé en base (avant, la valeur publique de
  docker-compose.yml permettait de forger un jeton admin).
- Le compte est relu en base à chaque requête : désactivation, changement
  de rôle et réinitialisation du mot de passe prennent effet immédiatement.
- Connexion : 10 échecs max par e-mail / 15 min, temps constant que l'e-mail
  existe ou non, mot de passe admin retiré des logs.
- Validation des entrées (ids, dates, mois, longueurs, e-mail) : 400 au
  lieu de 500. Un admin ne peut plus se désactiver ni se rétrograder.
- Mots de passe : 8 caractères minimum ; changement en libre-service.
- Export : nom de fichier conforme RFC 5987 (un nom de société avec « — »
  faisait planter l'export).
- esc() échappe aussi les guillemets (injection d'attributs HTML).
- En-têtes CSP / X-Frame-Options / nosniff (Nginx + API), API et Postgres
  publiés sur 127.0.0.1 seulement, image backend non-root via npm ci.

Optimisations
- Export : une requête pour tout le mois au lieu d'une par cadre.
- Saisie groupée : un seul INSERT (unnest), doublons dédupliqués.
- Dates renvoyées en chaînes (plus de décalage d'un jour selon le TZ).
- Planning : chaque clic met à jour l'affichage localement au lieu de
  recharger le mois ; les réponses de mois périmées sont ignorées.
- Recherche Utilisateurs / Plannings filtrée localement (plus une requête
  par touche) ; statuts des sociétés chargés en parallèle.

UI/UX
- Mobile : toutes les destinations dans la barre basse (Sociétés et Ma
  saisie étaient inaccessibles à l'admin) ; tableaux affichés en cartes
  (les boutons d'action étaient hors écran).
- Boutons désactivés pendant l'envoi, focus et Échap dans les dialogues,
  retour à l'écran de connexion quand la session est révoquée, erreurs
  d'export affichées au lieu d'un fichier JSON téléchargé, actions
  destructives signalées, confirmation avant désactivation.

+- Mots de passe hachés (bcrypt), 8 caractères minimum.
+- Session par cookie `httpOnly` / `SameSite=Lax` (12 h). Passez `COOKIE_SECURE: "true"` si l'application est servie en HTTPS.
+- Le compte est relu en base à chaque requête : désactiver un compte, changer son rôle ou réinitialiser son mot de passe prend effet immédiatement, sans attendre l'expiration de la session.
+- Connexion limitée à 10 échecs par adresse e-mail sur 15 minutes.
+- Un administrateur ne peut ni désactiver ni rétrograder son propre compte.
+- En-têtes de sécurité (CSP, `X-Frame-Options`, `nosniff`…) posés par Nginx et par l'API.
