Fix Home Assistant MQTT discovery deprecation warnings (#48)

* Fix Home Assistant MQTT discovery deprecation warnings

Replace deprecated 'object_id' with 'default_entity_id' in MQTT discovery messages
to fix Home Assistant Core 2026.4 compatibility warnings for all entities:
- Vehicle connected sensor
- Vehicle charging sensor
- Charging power sensor
- Charging current sensor
- Charging current limit sensor
- Energy meter sensor
- Temperature sensor
- Enable charging switch
- Charging current limit control

* Add Lilygo build to CI workflow with firmware artifacts
