fix: Update external config files to use 0.10 lot size

ROOT CAUSE FOUND:
User was right - there was an external config file!
advanced_position_management.py had hardcoded values:
- base_risk = 0.01 (should be 0.02)
- return 0.01 fallback (should be 0.10)
- No min/max lot enforcement

CHANGES:

1. advanced_position_management.py:
   ✅ base_risk: 0.01 → 0.02 (2% risk)
   ✅ return fallback: 0.01 → 0.10
   ✅ volume_min: max(broker_min, 0.10)
   ✅ volume_max: min(broker_max, 0.20)

2. session_filter_patch.py:
   ✅ Added lot sizing config:
      - min_lot: 0.10
      - max_lot: 0.20
      - default_lot: 0.10

IMPACT:
- Bot will now use 0.10 minimum lot
- Adaptive sizing respects 0.10-0.20 range
- No more 0.01 lot trades

TESTING NEEDED:
1. Restart kernel
2. Reimport advanced_position_management
3. Verify next trade uses 0.10 lot
