Add offline energy mechanism observability

[XiaoPengYouCode]

Summary

• add offline energy mechanism feedback routing so offline video simulation can run the energy mechanism route
• fix 2-class energy mechanism decode mapping for the current ONNX model contract
• add Rerun observability for energy mechanism center, blade center, prediction horizon, and key time-series

Verification

• cargo fmt --all -- --check
• cargo clippy --locked --workspace --all-targets -- -D warnings
• cargo test --locked --workspace --all-targets
