fix(gpu): wire PPO GPU experience collection, fix debug log levels, increase hyperopt deadline

- Wire GPU experience collection into PPO hyperopt adapter with CPU fallback
  (ensure_gpu_data, gpu_collect_trajectories, batch-to-trajectory converter)
- Downgrade 6 ERROR-level debug logs to debug!() in DQN hyperopt adapter
- Increase hyperopt activeDeadlineSeconds from 1h to 6h (job-template + train.sh)
- Mark 3 data-dependent real_data_loader tests as #[ignore]
- Fix 4 clippy map_or → is_none_or warnings in trading_service
