docs: Remove obsolete volume_mode references from documentation

The volume_mode parameter is no longer used since workflows now upload files to MinIO storage instead of mounting volumes directly. This commit removes all references to volume_mode from:

- Backend API documentation (README.md)
- Tutorial getting started guide
- MCP integration guide
- CLI AI reference documentation
- SDK documentation and examples
- Test project documentation

All curl examples and code samples have been updated to reflect the current MinIO-based file upload approach.
