API + data integrity
- /api/settings GET no longer leaks the active Anthropic API key — returns a
masked preview (sk-ant-XX…YYYY) plus a boolean `anthropic_api_key_set` flag
- /api/settings POST won't overwrite a real key with the masked placeholder
the client receives back on GET (length<30 / "…" / "..." / "***" markers
trigger a preserve-existing path)
- /api/best_result, /api/status, _make_run_dict, _result_to_dict, all AI-loop
emits, validation_run_complete, optimization_complete, ai_iteration_complete,
ai_targets_met, run_complete: max_drawdown and win_rate are now consistently
emitted as PERCENTAGES (0–100), matching the dashboard's existing display
formatters. They were previously emitted as fractions (0.13 = 13%) so the UI
rendered "0.13%" instead of "13%"
- ResultRanker.make_result() now sets `passing` and `raw_score` on every result
it produces. Previously these were only set during a full ranker.rank() pass,
so individual Phase 2 / Phase 3 runs hit _make_run_dict with passing=False
even when they cleared all gates (history showed "0 passing" when 22/22
actually passed)
