Remove hardcoded /workspace defaults from files.py

- Remove hardcoded container_workspace_path = '/workspace' default
- Remove hardcoded host_workspace_path = '/tmp/workspace' fallback
- Function now requires proper sandbox.volumes configuration
- Prevents file access when no volumes are configured
