Fix blank page issue and implement working chart
## Fixed Issues: - ✅ Resolved blank page caused by problematic chart component imports - ✅ Removed broken chart components that had library compatibility issues - ✅ Created SimpleChart component using HTML5 Canvas that works reliably - ✅ Cleaned up test pages and unused components ## Working Features: - ✅ Trading page loads correctly without blank screen - ✅ Professional candlestick chart with grid lines and price labels - ✅ Clean trading interface with all panels visible - ✅ No more loading errors or component failures ## Technical Implementation: - Used native HTML5 Canvas API for chart rendering - Proper TypeScript types and error handling - Responsive design that works in Docker environment - No external library dependencies to cause conflicts The trading dashboard is now stable and functional.
