Strip all 413 #[allow(dead_code)] annotations from 139 files and remove
the actual dead code they were suppressing: unused struct fields (and their
constructor sites), unused methods/functions, and entire dead structs.
Key removals:
- trading_engine compliance: ~50 dead structs/fields across audit, reporting, SOX modules
- trading_service: dead execution engine fields, broker routing, paper trading methods
- ml_training_service: dead TLS validation (~340 lines), GPU state, monitoring fields
- backtesting_service: dead model cache, TLS validation, TradeSignal fields
- risk: dead VaR engine fields, safety coordinator fields, position tracker fields
- adaptive-strategy: dead ensemble methods, regime detection, sizing functions
147 files changed, -4264 net lines. Workspace compiles with 0 errors.
