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:
- 500 errors when creating events due to storage permission issues
- React error #130 that occurred during event creation
- Consistent storage path handling across all services
