v0.3.0-beta.15

Beta pre-release for testing the Kobra X camera-light startup behavior.\n\n- Sets the initial Kobra X camera-light command type to the Anycubic value observed from Slicer/MQTT, so Home Assistant no longer needs a prior Slicer light toggle after restart.\n- Keeps the Anycubic Cloud panel version synchronized with the release.\n- Release Gate: https://github.com/ljschmitt/hass-anycubic_cloud_v3/actions/runs/28493977155
