Subject: [PATCH] fix(sync): ranking dedup + copy logs over HTTP
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- ranking.js: déduplique par (gencod, site) avant batchUpsert pour éviter
  "ON CONFLICT DO UPDATE command cannot affect row a second time"
- server.js: bouton "Copier les logs" utilise execCommand fallback quand
  navigator.clipboard indisponible (accès HTTP sans HTTPS)
