feat: refactor project structure and update dependencies

- Rename app_ui.py to main.py for better naming convention
- Update balance.py import to use dm_imu_pkg.dm_imu_py for modularity
- Constrain Gradio version to <5.0 in pyproject.toml and <6.0 in PKG-INFO for compatibility
- Add compiled .so file for dm_imu_pkg and update cached .pyc files after builds
- Include motors_enabled flag in main.py UI for better state management

These changes improve code organization, resolve potential import issues, and ensure dependency compatibility in the balance controller project.
