🔍 Add comprehensive startup health check for deployment monitoring

Added startup diagnostics to catch deployment issues early:
- Verify all critical files exist in expected locations
- Test GAIASolver import before app starts
- Check environment variables are properly set
- Detailed logging for troubleshooting
- Applied to both /home/user/app.py and /home/user/app/app.py

This will prevent silent failures and provide clear diagnostics
if deployment issues occur in the future.
