New BacktestPanel: shows qualified hit-rate/expectancy vs the all-setups baseline, a by-direction breakdown, and the probability calibration table (predicted vs realized, over-confident buckets flagged amber). Includes a "Run backtest" button that triggers the job and a plain explanation of the method and its limits. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
