jgrusewski 3278cec29b perf: PPO zero-copy fold loop — train_from_slices + delete train_ppo_fold ...

Add PpoTrainer::train_from_slices(&[[f64; 42]]) that converts to
Vec<Vec<f32>> internally (PPO train() API requires ownership). Replace
the PPO fold loop in train_baseline_rl.rs: eliminates the OHLCVBar
construction shim and calls train_from_slices directly on fxcache
feature slices. Delete the standalone train_ppo_fold function entirely.
