Implement CLI app for API interaction with MFA

- Create full CLI application with authentication, sync triggering, and status checking
- Implement MFA support for secure authentication
- Add token management with secure local storage
- Create API client for backend communication
- Implement data models for User Session, Sync Job, and Authentication Token
- Add command-line interface with auth and sync commands
- Include unit and integration tests
- Follow project constitution standards for Python 3.13, type hints, and code quality
- Support multiple output formats (table, JSON, CSV)
