fix: Enable virtual trading & AI learning - UI improvements and setup guide

- Add comprehensive setup guide (VIRTUAL_TRADING_SETUP_GUIDE.md)
- Improve UI to clearly show required steps for AI learning
- Make auto-execute toggle always visible with clear instructions
- Add blue info panel explaining the learning setup process
- User can now easily enable: Continuous Learning + Auto-Execute
- Virtual trades will execute automatically and AI will learn from outcomes

Resolves issue: AI analyzing without learning due to missing virtual trade execution
