🚀 Fix position sizing and add real wallet balance integration

Fixed Position Size Calculation:
- Changed input from SOL to USD for clarity
- Fixed calculation: positionSizeSOL = positionValueUSD / coinPrice
- Resolved issue where entering 0.4 SOL showed incorrect 0.0025 underneath

- Added slider for smooth position adjustment ( to full balance)
- Percentage buttons (25%, 50%, 75%, 100%) now accurate
- Real-time display shows both USD and SOL amounts
- Live percentage display of balance usage

 Added Wallet Overview to Dashboard:
- Main dashboard shows real wallet balance prominently
- Trading page displays actual wallet holdings
- StatusOverview component enhanced with wallet info

- Accurate position sizing based on actual 3.40 balance
- Intuitive slider + percentage buttons
- Real-time balance updates every 30 seconds
