mindesbunister 0e3a2d7255 feat: Implement Jupiter-style trading interface with token selection
- Add 'You're paying' and 'You're receiving' sections with proper token dropdowns
- Implement balance display and MAX button functionality
- Add automatic receiving amount calculation based on paying amount
- Enhance token selector with icons, names, and balance information
- Improve leverage position value calculations and risk warnings
- Update trade execution to use new paying/receiving token structure
- Maintain all existing functionality including stop loss, take profit, and position management

This creates a more intuitive and professional trading interface that matches Jupiter's UX patterns.
