feat(user) : UI archivage/désarchivage des utilisateurs côté admin

- badge « Archivé » et libellé barré dans la liste admin
- popup de confirmation avant archivage (rappelle que c'est réversible)
- bouton de restauration (PATCH archived:false) pour les archivés
- case « Afficher les utilisateurs archivés » (filtre ?archived=true)
- masque l'action d'archivage sur son propre compte (évite le 403)
- service users : getArchived/restore, toast remove -> users.archived
- i18n FR : clés archived/restored/badge/confirmation

-### Configuration réseau (HTTP)
+### Configuration réseau (HTTP) — par poste, hors git
+
+Le transport HTTP nécessite un **token API** (Bearer), qui est un **secret** : il ne va **jamais**
+dans le `.mcp.json` versionné (celui-ci ne contient que le serveur STDIO local, sans secret).
+Chaque développeur configure le serveur HTTP dans sa **config Claude Code locale**.
+
+**Méthode recommandée (identique sur Fedora, Windows et macOS) :**
+
+```bash
+claude mcp add --transport http --scope user lesstime \
+  http://project.malio-dev.fr/_mcp \
+  --header "Authorization: Bearer <api-token>"
+```
+- En prod : `http://project.malio-dev.fr/_mcp`
+- En réseau local : `http://<ip-serveur>:8082/_mcp`
+
+**Où c'est stocké** (si tu édites le fichier à la main, sous la clé `mcpServers`) :
+
+| OS | Fichier de config Claude Code |
+|----|-------------------------------|
+| **Fedora / Linux** | `~/.claude.json` |
+| **Windows** (collègue) | `%USERPROFILE%\.claude.json` (ex. `C:\Users\<user>\.claude.json`) |
+| **macOS** | `~/.claude.json` |
 
 ```json
 {
   "mcpServers": {
     "lesstime": {
-      "type": "url",
+      "type": "http",
-      "url": "http://<ip-serveur>:8082/_mcp",
+      "url": "http://project.malio-dev.fr/_mcp",
-      "headers": {
+      "headers": { "Authorization": "Bearer <api-token>" }
-        "Authorization": "Bearer <api-token>"
-      }
     }
   }
 }
 ```
 
+Après modification, relancer la connexion avec `/mcp` dans Claude Code.
+
 ### Gestion des tokens API
 
+Générer / régénérer un token pour un utilisateur :
+
 ```bash
+# En dev (container local)
 docker exec -u www-data php-lesstime-fpm php bin/console app:generate-api-token <username>
+
+# En prod (sur le serveur, dans infra/prod)
+sudo docker compose exec -T -u www-data app php bin/console app:generate-api-token <username>
 ```
 
+⚠️ Le token est **invalidé à chaque reset/reseed de la base**. Symptôme : `/mcp` renvoie
+`HTTP 401 "Invalid API token"`. Il faut alors le **régénérer** (commande ci-dessus) puis remplacer
+la valeur `Bearer ...` dans ta config locale (par poste).
