Improve alpha research selection and submission verification

Implement adaptive seed pool with family-grouped empirical weights and retired dead-ends

feat: implement v2.4 campaign theme compliance patch with dynamic tags (PowerPoolSelected, RegularAlpha) and pure power pool theme guards (HTVR ratio >= 0.75, pv1 dataset ban)

feat: tag PowerPoolSelected in submission PATCH and enforce date-based strict theme rules (HTVR test and dataset bans) locally in evaluator

feat: QuantForge v2.3 - dynamic Sharpe evaluator, proactive auth, relative rate limits, and raised polls timeout

Introduce ExpressionFactory grammar generator, store raw result payload in DB, and handle incomplete/timeout simulation statuses

fix: rescue 71 stuck SIMULATING alphas on boot; lower Sharpe pre-filter 1.5->1.2 to unblock submissions

Execute Phase 13.5: Support High Turnover (HTVR) Campaign with evaluator thresholds, lookback constraints, and boosted USA regional weight

Phase 7: Analytics dashboard overhaul - trash_reason tracking, enriched /api/stats, Semaphore(11), premium dark/light UI, LLM router model tracking, pause/resume endpoints

Implement sequential LLM request staggering, infinite WQ concurrent simulation limit retries, and clean None metrics trashing in evaluator
