3b4e035819 fix: IV rank fallback to history when live options fetch fails + Entrée date from cycle logs 
- iv_engine/options_vol: when get_atm_iv() returns None (yfinance chain unavailable),
  fall back to most recent iv_history row so IV Rank is always computable from
  bootstrapped data; live vs history source tagged as iv_source field
- Dashboard: build mtmMap from tradeMtmData.trades (trade_entry_prices, cycle auto-log)
  keyed by pattern_id; getAddedInfo() falls back to mtmMap so Entrée/Durée columns
  populate automatically after each AI cycle without manual portfolio add
- OptionsLab: show '~' prefix and 'IV estimée' label when IV comes from history fallback;
  fix near-invisible text-slate-700 on 'Sans historique' section header

97ba36454b fix: bootstrap IV history with 1y realized vol to unblock IV Rank from 50 
IV Rank was stuck at 50 for all tickers because the formula returns 50.0
when iv_max == iv_min (not enough historical snapshots). Added:
- bootstrap_iv_history(): downloads 1y of closes per ticker, computes
  30d rolling realized vol (annualized), saves each day to iv_history
- POST /api/options-vol/bootstrap-history endpoint (runs in background)
- OptionsLab: auto-detect when IV Rank needs bootstrapping and show
  an amber banner with one-click "Initialiser historique" button

9a6b6f70b1 feat: Phase 1 — IV Rank, Term Structure, Skew, Options Flow (Sprint 1.1/1.2/1.3) 
Backend:
- iv_engine.py: ATM IV, term structure (30/60/90/180j), put/call skew,
  options flow (P/C OI ratio, unusual strikes, gamma bias), proxy map for futures→ETFs
- database.py: iv_history table + save_iv_snapshot, get_iv_rank_percentile, get_iv_history
- routers/options_vol.py: /api/options-vol/ endpoints (snapshot, batch, watchlist, history)
- auto_cycle.py: inject IV context string into scoring prompt (step 3.5)
- ai_analyzer.py: score_patterns_with_context accepts iv_context param
- main.py: register options_vol router

Frontend:
- pages/OptionsLab.tsx: full IV dashboard (watchlist by IVR, term structure, skew, flow, sparkline)
- pages/JournalDeBord.tsx: IvRankCell component + IV Rank column per trade
- hooks/useApi.ts: useIvSnapshot, useIvWatchlist, useIvBatch, useIvHistory, useIvForTrade
