fix: remove 0.7 ATR multiplier, store risk_distance in DB

Browse Source 
- Removed 0.7*ATR multiplier from signal_engine and paper_monitor
- risk_distance now stored per-trade in paper_trades table
- paper_monitor/signal_engine read risk_distance from DB (no hardcoded values)
- V5.1 TP/SL: 2.0/1.5/3.0 -> 1.4/1.05/2.1 (same actual distance)
- V5.2 TP/SL: 3.0/2.0/4.5 -> 2.1/1.4/3.15 (same actual distance)
- Fixed V5.2 pnl_r: all historical values corrected by *2/3
- API unrealized_pnl_r also reads from DB risk_distance
