🏗️ MAJOR ARCHITECTURAL FIXES: Resolve critical compilation errors and architectural violations

✅ FIXED CRITICAL COMPILATION ERRORS:
- ProductionBenzingaProvider: Added missing Debug trait
- Trading Service: Fixed Option<f64> to f64 conversion in order book levels
- TLS Config: Fixed certificate ownership and lifetime issues
- Repository Impl: Fixed unused variable warnings with underscore prefix
- Config Database: Fixed sqlx lifetime parameter errors
- Common Types: Removed invalid Side import causing compilation failure

🔧 ARCHITECTURAL COMPLIANCE ACHIEVED:
- Config Crate Centralization: All vault access properly routed through config crate
- TLI Pure Client: No server components, clean gRPC client architecture
- Service Independence: Trading/Backtesting/ML services properly decoupled
- Repository Pattern: Clean dependency injection without database coupling

🎯 DEPENDENCY MANAGEMENT CORRECTED:
- Fixed circular dependencies between services
- Centralized configuration through config crate only
- Removed direct vault dependencies outside config crate
- Clean import structure across all services

📊 COMPILATION PROGRESS:
- From 100+ critical errors to manageable type imports
- Core architectural violations resolved
- Clean service boundaries established
- Repository interfaces properly abstracted

🚀 NEXT PHASE READY:
- Common type exports need completion
- Final import reconciliation pending
- Zero errors target within reach
