feat(backend): consolidation finale Spec 001 LCB-FT + Flyway V1-V5

Migrations Flyway (consolidées) :
- V1 : Schéma complet (69 tables, 1322 lignes)
- V2 : Colonnes BaseEntity (cree_par, modifie_par)
- V3 : Colonnes métier manquantes (adresses, alert_configuration)
- V4 : Correction system_logs (renommage colonnes, ajout timestamp)
- V5 : Nettoyage alert_configuration (suppression colonnes obsolètes)
- Suppression V2-V6 obsolètes (fragmentés)

Entités LCB-FT :
- AlerteLcbFt : Alertes anti-blanchiment
- AlertConfiguration : Configuration alertes
- SystemAlert : Alertes système
- SystemLog : Logs techniques (DÉJÀ COMMITÉE avec super.onCreate fix)

Services LCB-FT (T015, T016) :
- AlerteLcbFtService + Resource : Dashboard alertes admin
- AlertMonitoringService : Surveillance transactions
- SystemLoggingService : Logs centralisés
- FileStorageService : Upload documents

Repositories :
- AlerteLcbFtRepository
- AlertConfigurationRepository
- SystemAlertRepository
- SystemLogRepository

Tests :
- GlobalExceptionMapperTest : 17 erreurs corrigées (toResponse())

Spec 001 : 27/27 tâches (100%)

+--              Ces colonnes font partie de BaseEntity et sont requises par

+-- ALTER TABLE nom_table ADD COLUMN IF NOT EXISTS modifie_par VARCHAR(255);
