Correct the trigger mechanism to match how Home Assistant event entities
actually work. Event entities trigger on state changes and expose the
actual event type as an attribute, not as event_data.
Changes:
- Replace platform:event trigger with platform:state
- Add condition to check event_type attribute for 'config_single'
- Remove incorrect event_data and state_changed event_type usage
This matches the working pattern used in production automations and
ensures the blueprint triggers correctly when the config button is
pressed on Inovelli switches.
