fix: correct 5 broken field names based on live API verification (#42)

Verified all 33 new fields against live TradingView scanner API.
Five field names were invalid (returned Unknown field error); replaced with
confirmed working names sourced from TradingView field reference:

- analyst_recommendations_buy → recommendation_buy
- analyst_recommendations_sell → recommendation_sell
- analyst_recommendations_neutral → recommendation_hold
- continuous_dividend_payout_years → continuous_dividend_payout
- dps_yoy_growth_ttm → dps_common_stock_prim_issue_yoy_growth_fy

All 28 other new fields confirmed working (non-null data for ≥9/10 top
market-cap stocks). Graham number formula verified exact: sqrt(22.5×EPS×BVPS).
