fix: translate machine_state sensor values; bump to 0.4.1

machine_state was rendering the raw lowercase OCF values (idle/active/
pause) untranslated in the UI. Add device_class=enum, options, and a
translation_key matching the existing pattern used by ice_making_status
and connection_mode, in both the shared operational.py capability and
oven.py's separate machine_state sensor.

Bump patch version for this fix plus the ice_type 'off' translation and
iot_class correction earlier on this branch.
