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.
