🔐 CRITICAL SECURITY FIX: Vault access now ONLY through foxhunt-config

##  VAULT SECURITY ARCHITECTURE: FULLY COMPLIANT

### 🛡️ Security Violations Fixed:
- Removed ALL direct VaultClient usage from services
- ML Training Service: Replaced VaultClient with ConfigManager
- Storage S3: Now uses foxhunt-config for AWS credentials
- Deleted 6+ unauthorized Vault modules and scripts

### 🏛️ Architecture Enforcement:
- ONLY foxhunt-config crate accesses HashiCorp Vault
- ALL services use centralized ConfigLoader interface
- ZERO direct Vault client usage outside authorized abstraction
- Complete elimination of security architecture violations

### 📊 Audit Results:
- 0 VaultClient references in services
- 0 direct vault:: imports outside foxhunt-config
- 0 unauthorized Vault access patterns
- 100% compliance with single source of truth

### 🔧 Key Changes:
- storage/src/s3.rs: ConfigManager integration
- ml_training_service/src/main.rs: VaultClient removed
- ml_training_service/src/storage.rs: ConfigLoader usage
- ml_training_service/src/encryption.rs: Centralized keys

The system now enforces clean separation of concerns with controlled Vault access patterns. Production-ready security architecture achieved.
