P5 — Mode consultation ciblée (Option B, implémentation complète)

Backend :
- Nouvelle table `consultations` (slug unique, fenêtre temporelle, webhook, logo)
- `ideas.consultation_id` FK nullable (NULL = contexte global home)
- `synthesis.consultation_id` FK nullable (synthèse par contexte)
- Boucle auto-fermeture (thread daemon, 60 s) — ferme + webhook à l'échéance
- Webhook de clôture : POST JSON (synthèse + métadonnées) via urllib.request
- Routes publiques : GET/POST /api/consultations/<slug>, synthèse, contributions, export/print
- Routes admin : list, create, close (+ webhook), delete (cascade explicite)
- CSP ajustée sur /export/print pour autoriser window.print()

Frontend :
- Nouvelle page /consultation/:slug — formulaire, synthèse live, contributions paginées, PDF
- Admin panel : onglet Consultations — liste, formulaire création, fermeture, suppression

Docs : DAT.md v1.5, DEX.md v1.7 (section P5, tables, routes, webhook)

+### 3.5 Consultations ciblées (P5)
+
+Le mode consultation permet à un organisateur (mairie, asso, collectif) de créer un espace thématique ciblé, accessible via `/consultation/<slug>`.
+
+**Caractéristiques** :
+- Fenêtre temporelle (`starts_at`, `ends_at`) avec fermeture automatique (boucle arrière-plan, 60 s)
+- Séparation stricte : `consultation_id IS NULL` = contribution globale (page d'accueil)
+- Synthèse indépendante par consultation (même mécanique IA, contexte isolé)
+- Webhook de clôture : POST JSON avec synthèse finale vers `webhook_url` configuré
+- Export HTML/PDF : `GET /api/consultations/<slug>/export/print`
+- Gestion complète dans le panel admin (onglet Consultations)
+
+**Boucle auto-fermeture** :
+```
+threading.Thread(target=_autoclose_consultations_loop, daemon=True).start()
+# → time.sleep(60) → get_consultations_to_autoclose() → close_consultation() → _trigger_webhook()

+
+### Créer une consultation (panel admin)
+
+1. Ouvrir `/admin` → onglet **Consultations** → **Nouvelle consultation**
+2. Remplir : slug (URL-safe, ex. `budget-mairie-2026`), titre, sujet
+3. Optionnel : message d'introduction, organisateur, logo HTTPS, dates, webhook
+4. Les dates sont interprétées comme UTC
+5. La consultation est immédiatement accessible sur `/consultation/<slug>`
+
+### Fermeture automatique
+
+La fermeture automatique est gérée par un thread arrière-plan (toutes les 60 secondes).
+Si `ends_at` est défini et dépassé, la consultation est fermée automatiquement et le webhook déclenché.
+
+```bash
+# Vérifier les consultations actives
+psql "$DATABASE_URL" -c "SELECT slug, title, starts_at, ends_at, closed_at FROM consultations;"
+```
+
+### Webhook de clôture
+
+Si `webhook_url` est configuré, un POST JSON est envoyé à la clôture :
+
+```json
+{
+  "event": "consultation_closed",
+  "consultation": {
+    "slug": "budget-mairie-2026",
+    "title": "Budget participatif 2026",
+    "closedAt": "2026-06-30T18:00:00+00:00"
+  },
+  "synthesis": {
+    "text": "...",
+    "ideaCount": 42
+  }
+}
+```
+
+### Export PDF d'une consultation
+
+```
+GET /api/consultations/<slug>/export/print
+```
+
+Retourne une page HTML auto-imprimante. Accessible depuis le bouton **Exporter PDF** sur la page de consultation, ou directement en navigateur.
