fix: Respect user trading mode choice in optimized automation

Frontend changes:
- Pass mode, tradingAmount, balancePercentage, dexProvider to optimized API
- Send user's actual trading mode choice (LIVE/SIMULATION)

Backend changes:
- Accept mode and trading parameters from frontend request
- Use passed mode instead of hardcoded 'SIMULATION'
- Apply user's trading amount and balance percentage settings

This fixes the issue where optimized automation always used SIMULATION
regardless of user's LIVE trading selection.
