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

- 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

+-- Migration 1.7.0 - Materialisation de la vue sessiondebriefs
+-- ============================================================
+-- Cible : MariaDB 10.4+.
+-- Idempotent : peut etre rejoue sans erreur. Le cache est entierement
+-- reconstruit a chaque execution (TRUNCATE + backfill).
+--
+-- Changement principal : la vue sessiondebriefs etait recalculee a chaque
+-- requete (12 LEFT JOIN + GROUP BY + sous-requetes correlees). Elle est
+-- desormais materialisee dans une vraie table session_debriefs_cache,
+-- peuplee :
+--   - en bulk au moment de cette migration (backfill toutes sessions),
+--   - puis par une procedure stockee rebuild_debrief_cache(p_session_id)
+--     appelee depuis le code PHP a chaque modification de session
+--     (session/stop, session/userleave, session/updateobjectives,
+--     events/storetriggerevent, events/storereactevent).
+--
+-- La vue sessiondebriefs garde son nom et ses colonnes : le code consommateur
+-- (stats_object.php : getResultsForSession, getUserHistory) ne change pas.
+-- Elle devient un simple passe-plat sur la table cache.
+--
+-- Action 2 (fix partiel du double JOIN participates) : la jointure PH
+-- (qui sert a determiner TargetRoleId/TargetRole) est desormais contrainte
+-- sur PH.userId = R.hitUserId au lieu de matcher tous les participants.
+-- Effet :
+--   * Pour les hits user-on-user : meme resultat (correct par construction).
+--   * Pour les hits NPC/objets : TargetRoleId vaut 3 (IA) au lieu d'un
+--     role aleatoire d'un autre participant. C'est un fix de bug.
+-- La jointure PS reste inchangee (preserve le fallback ShooterId quand T est NULL).
