feat: publicites - add total/pages to list, add /historique endpoint

- List endpoint now returns total count and pages for pagination
- Added statut filter (en_cours/passees/futures) to list endpoint
- Added GET /historique using pub_entetes for complete pub history
  (pub_ecoulement only has recent data; pub_entetes has all 95 pubs)
- /historique returns nb_sites, ca_total, qte_totale via LEFT JOIN
