Fix storage path issues and React error #130

Backend fixes:
- Add STORAGE_PATH environment variable support
- Fix absolute path references in all backend services
- Update Docker configuration with correct storage path

Frontend fixes:
- Remove individual ErrorBoundary wrappers to fix React error #130
- Remove unused ErrorBoundary import
- Simplify route structure to prevent component mounting issues

This resolves:
