jgrusewski 04d8802c94 refactor: remove 8 always-on use_ booleans — features are mandatory
Remove use_double_dqn, use_dueling, use_per, use_branching,
use_distributional, use_noisy_nets, use_huber_loss, and use_cql
from DQNConfig, DQNHyperparameters, and DqnParams structs.

These features are always enabled (Rainbow DQN standard). The boolean
flags were dead code — every constructor set them to true, and the
only code paths that set them to false were in tests that disabled
features for simplicity. With the fields removed, the features are
unconditionally active, eliminating ~490 lines of dead configuration.

Key changes:
- Struct field declarations removed from 3 core config structs
- Conditional branches (if use_X { ... } else { ... }) simplified:
  dueling/branching/PER network creation is now unconditional
- Checkpoint metadata hardcodes "true" for backward compatibility
- Hyperopt search space index 11 (use_branching) fixed at 1.0
- TOML/YAML config files cleaned of removed fields
- Tests that toggled these flags updated or rewritten

45 files changed, -487 net lines. Zero new test failures.

//! Ensemble pipeline validation with REAL trained DQN and PPO models.
//!
//! This test proves the full pipeline: train DQN -> train PPO -> get real
//! predictions from both -> aggregate through the ensemble's SignalAggregator
//! -> produce valid EnsembleDecision values.
//!
//! No mocks are used for model inference. The DQN and PPO are trained on
//! real 6E.FUT minute-bar data, then their actual forward passes produce
//! predictions that flow through the ensemble aggregation engine.
//!
//! Requires: `test_data/real/databento/6E.FUT_ohlcv-1m_*.dbn` to exist.
//! Run with:
//! SQLX_OFFLINE=true cargo test --manifest-path ml/Cargo.toml \
//! --test ensemble_real_models_validation_test -- --nocapture
