fix: log execution result fields before assertions for CI diagnostics

BacktestWorkflow now logs instrument/strategyId/pnl/trades at INFO level
after each execution poll completes. BacktestIntegrationTest logs the full
ResultMap and individual fields unconditionally before any assertion, so
transient backend anomalies leave a trace in CI output.

The CI failure (strategyId=null) was a transient backend issue — confirmed
by local re-run returning the field correctly.
