fix: 6 workflow flaws detected via full system test

1. CRITICAL FIX - Reports 500 Internal Server Error: Root cause: {{}} in onclick was Jinja2 template expression Fix: Changed to single {} in reports_index.html onclick 2. Score history chart always empty: Root cause: score_update only emitted inside wfv.passed block Fix: Emit score_update after every hypothesis run with {promoted:false} Fix: Baseline run also pushes to chart via run_complete handler 3. IS gate too strict - optimizer produces 0 candidates forever: Root cause: min_calmar=0.35 but best EA has calmar=0.165 Fix: Two-tier IS check - passes if composite_score improves vs baseline (absolute thresholds still apply as alternative pass condition) 4. Findings emitted twice (double UI display): Root cause: baseline analyzed once after run, then re-analyzed in iter 1 Fix: Cache baseline findings, reuse in iteration 1 without re-emitting 5. Chart labels improved: 'Baseline' for first point, 'It1·h1' for hypothesis runs Calmar normalized -0.5..2.0 -> 0..1 for chart display 6. Best score header only updates on actual promotion (not per-hypothesis)
