fix: correct entry prices and position sizing in trading system

- Fixed automation service to use real SOL price (~89) instead of hardcoded 00
- Updated position size calculation to properly convert USD investment to token amount
- Enhanced trade display to show separate entry/exit prices with price difference
- Added data quality warnings for trades with missing exit data
- Updated API to use current SOL price (189.50) and improved trade result determination
- Added detection and warnings for old trades with incorrect price data

Resolves issue where trades showed 9-100 entry prices instead of real SOL price of 89
and position sizes of 2.04 SOL instead of correct ~0.53 SOL for 00 investment
