Fixes A/B/C/D incident rebond EDF nuit 07-08/08 + GRAFCET doc

- A: état collant night_recovery_done_idle + bande cible−2 (anti-rebond takeover)
- B: snapshot relit night_session_start_soc/at (fin des réécritures 30s)
- C: hystérésis grid — turn_off_vehicle_unplugged (coupure immédiate, bypass min_on)
- D: evcs_status_raw==3 (charged) = fin de charge immédiate
- golden 19→23 scénarios (2 attendus mis à jour, 4 nouveaux)
- MANUEL_COMPLET §11.6 GRAFCET cycle nuit, HANDOFF §17, vision-notes incident
