feat: Centralize trading configuration

PROBLEM:
- User identified lot size settings were chaotic and scattered
- Settings across 3 cells (23, 25, 47) caused confusion
- Multiple attempts needed to fix lot size (0.01 → 0.05 → 0.10)
- Quote: "mir kommt das ganze ein bisschen chaotisch vor"

SOLUTION:
✅ Created centralized TRADING_CONFIG in new Cell 6
✅ Updated Cell 25 (calculate_position_size) to use config
✅ Updated Cell 27 (execute_trade_v2_adaptive) to use config
✅ Updated Cell 49 (ADAPTIVE_COMPLETE_CONFIG) to reference config

CONFIGURATION STRUCTURE:
- lot_sizing: min/max/default lot sizes
- risk: max_risk_per_trade, max_positions, max_daily_loss
- confidence: thresholds per session
- atr: base_multiplier, period
- news_filter: enabled, minutes_before/after
- sessions: enabled sessions
- symbols: primary trading symbol

BENEFITS:
✅ Single source of truth for all settings
✅ Easy to find and change configuration
✅ Clear documentation in one place
✅ Prevents scattered hardcoded values
✅ Future changes require only editing Cell 6

FILES:
- centralize_config.py: Script to add config cells
- update_cells_to_use_config.py: Updates cells to use config

NEXT STEPS:
1. Restart kernel in Jupyter
2. Run Cell 6 (TRADING_CONFIG)
3. Run all other cells
4. Verify bot uses 0.10 lot size
