fix: move revenueholdings-license to optional [license] extra with graceful import fallback

- Remove revenueholdings-license>=0.1.0 from required dependencies
- Add license optional-dependencies group with revenueholdings-license
- Make require_license() import conditional: try/except ImportError
- On ImportError, define no-op require_license() and print warning
- Fixes CI breakage caused by revenueholdings-license not on PyPI (COM-79, COM-82, COM-83)
