Fix three compilation errors in the observability module that had been
commented out due to type errors with tracing_subscriber:
- Fix lifetime issue in set_correlation_id by cloning Arc before async
- Fix Option<CorrelationId> vs CorrelationId type mismatch in get_correlation_id
- Update deprecated opentelemetry_sdk::trace::Config API to builder methods
- Remove unused imports across all observability submodules

Add #![deny(clippy::unwrap_used, clippy::expect_used)] to api_gateway and
backtesting_service crate roots. The ml and common crates already had these
deny attributes.
Production code fixes:
- api_gateway: replace expect with unwrap_or for cache stats and LRU eviction
- api_gateway: add #[allow] on NonZeroU32 constants and Prometheus metrics
- backtesting_service: replace expect/unwrap with ok_or_else/? for OHLCV
bar bounds checks and chrono timestamp resampling
- backtesting_service: add #[allow] on Prometheus Lazy metric statics
Test code: cfg_attr(test, allow) at crate root for both crates.

Replace three placeholder stubs that returned Err("pending") with
working implementations that create real trainers and run actual
training loops:
- train_ppo: Creates PpoTrainer with conservative defaults,
loads market data as state vectors, runs PPO training with
progress callback, saves checkpoint metadata
- train_mamba2: Creates Mamba2Trainer with validated hyperparams,
generates training/validation tensor pairs, runs MAMBA-2
sequence training, collects training statistics
- train_tft: Creates TFTTrainer with FileSystemStorage, attempts
Parquet data loading first with synthetic data fallback,
runs TFT training with OOM retry support
Also fixes 10 pre-existing compilation errors:
- Import PPOHyperparameters/PPOTrainer -> PpoHyperparameters/PpoTrainer
- Import TFTHyperparameters -> TFTTrainerConfig (correct type name)
- ModelType::LIQUID -> ModelType::LNN (correct enum variant)
- DQNHyperparameters struct literal -> conservative() with overrides
- checkpoint_manager.config() -> direct PathBuf construction
- DQN checkpoint callback 2-arg -> 3-arg (epoch, data, is_best)
- opts partial move -> clone version_tag before unwrap_or_else
- Add catch-all arm for exhaustive ModelType matching
- Add FileSystemStorage import for TFT trainer construction
- Prefix unused variables with underscore

Replace the TODO placeholder with proper CRL validation that checks:
- thisUpdate is not in the future (CRL not yet valid)
- nextUpdate is not in the past (CRL expired)
- CRL issuer matches the certificate issuer (prevents CRL substitution)
All checks use x509-parser's ASN1Time for accurate time comparison
and log warnings/errors via tracing for operational visibility.

Production trading must never rely on simulated predictions. The ensemble
coordinator now requires real model adapters and returns errors when none
are registered or all fail inference, instead of silently falling back to
mock/simulated predictions.

Replace empty placeholder safetensors file with actual model weight
serialization using the VarMap, matching the DQN trainable adapter pattern.

Replace the TODO stub in validate_certificate_chain with full
cryptographic chain-of-trust verification using x509-parser's ring-backed
verify feature:
1. Issuer CN matching -- client cert issuer must equal CA subject CN
2. CA validity period -- reject expired or not-yet-valid CA certificates
3. CA Basic Constraints -- verify the signer actually has cA=true
4. Cryptographic signature -- verify client cert TBS data signature
against the CA's SubjectPublicKeyInfo (RSA/ECDSA/Ed25519 via ring)
Also enables the "verify" feature on x509-parser and extends the method
signature to accept ca_cert_pem for proper chain validation.

Replace 6 unwrap() calls with safe error handling in DQN IQN code:
- Production: 3 unwrap() on iqn_network/iqn_target_network replaced with
ok_or_else returning MLError::ModelError for clear diagnostics
- Tests: 2 result.unwrap() replaced with ?, 2 DQN::new().unwrap() replaced
with ? after changing test signatures to return anyhow::Result<()>

PerformanceTracker now records open entries, computes realized PnL on

BacktestMLModel bridges ModelInferenceAdapter → MLModel trait for the

Converts Trade, Ohlcv, and Quote variants from data::ProcessedMessage
to trading_engine::MarketEvent. Handles HardwareTimestamp→DateTime<Utc>,
Decimal→Quantity, and String→Symbol type conversions.

The catch-all match arm in convert_to_common_event was creating synthetic
TradeEvent objects with symbol "UNKNOWN", price zero, and trade_id "placeholder"
for any MarketDataEvent variant not explicitly handled (Bar, OrderBook, News, etc.).
These fake trades corrupt downstream analytics pipelines. Now returns None and
logs at debug level instead, allowing callers to filter unsupported types cleanly.
