Update inovelli_mode_cycling blueprint to use event entity

Change from sensor-based to event-based trigger for Inovelli button
presses. This aligns with Zigbee2MQTT's modern event entity approach
and matches the Phase 1 plan specification.

Changes:
- Replace switch_action_sensor (sensor domain) with switch_action_event (event domain)
- Update trigger from platform:state to platform:event with event_data
- Use state_changed event type for proper event handling

This provides more reliable button press detection and cleaner event
handling compared to the older sensor state monitoring approach.
