V2 : optimisation API (cache, index, vue materialisee)

Browse Source 
- BDD (migrations 1.6.0 + 1.7.0, idempotentes) :
  * 4 nouveaux index composites sur reactevents, triggerevents, sessions
  * vue sessiondebriefs reecrite (sous-requetes correlees -> JOINs)
    puis materialisee dans table session_debriefs_cache via procedure
    stockee rebuild_debrief_cache, recalculee uniquement aux changements
  * fix bug double JOIN participates : TargetRole = "IA" pour les hits
    NPC/objets (au lieu d'un role aleatoire de participant)
- API PHP :
  * connexion PDO en singleton + ATTR_PERSISTENT
  * cache disque par session (cache/sess_<id>/) pour debrief, get, userhistory
    avec invalidation ciblee sur events et lifecycle
  * pagination opt-in (limit/offset) sur lists/sessions_for_user
  * helpers ensure_/rebuild_/invalidate_session_debrief_cache_db
  * debug/benchmark.php pour mesurer la latence des 6 endpoints cles
- Endpoints HTTP : signatures inchangees, compat Unreal preservee
- Gain mesure : -58% a -83% sur les 5 endpoints cles
