CRITICAL FIX: Resolve trade validation amountUSD passing issue

- Fixed execute-dex API to extract and forward amountUSD parameter from request body
- Updated AIAnalysisPanel to pass amountUSD in executeTrade function call
- Fixed port references in validation and execute-dex APIs to use current dev server port
- Resolves issue where amountUSD was undefined in validation causing incorrect balance calculations
- Added comprehensive logging for debugging trade data flow
- Tested successfully: 5 USD trade now validates correctly instead of requiring 832.5 USD
