feat: Update Telegram bot ATR to match actual SOL data

Data Analysis (162 SOL trades):
- Average ATR: 0.407 absolute
- Median ATR: 0.43 absolute (~0.32% of price)
- Range: 0.24-0.66 absolute

Updated MANUAL_METRICS:
- Old: atr = 0.45 (estimated)
- New: atr = 0.43 (data-driven median)

Impact on manual Telegram trades:
- TP1: 0.43 × 2.0 = 0.86% (vs 0.90%)
- TP2: 0.43 × 4.0 = 1.72% (vs 1.80%)
- SL: 0.43 × 3.0 = 1.29% (vs 1.35%)

Slightly tighter but more accurate to actual SOL volatility.
