fix: Add signal_info_override and confidence_override to execute_trade_v2_adaptive

PROBLEM:
- execute_trade_v2_adaptive didn't accept pre-calculated signal_info
- Function did its own signal analysis internally
- Trying to pass entry_signal/signal_info caused parameter errors

SOLUTION:
- Added optional parameters: signal_info_override, confidence_override
- If provided, function uses pre-calculated values
- If not provided, function calculates values itself (backward compatible)

CHANGES:
- Cell 28: Added new parameters to function signature
- Cell 28: Use signal_info_override if provided
- Cell 28: Use confidence_override if provided
- Cells 85, 90: Updated execute_trade calls to use new parameters
- activate_enhanced_scoring.py: Updated to use new parameters

Now enhanced_trading_check_wrapper can pass its hybrid confidence
score to execute_trade_v2_adaptive properly.
