This commit fixes the MQTT discovery payload structure to match the working
v1 implementation and comply with Home Assistant's MQTT discovery specification.
Key changes:
- Add "type" field to discovery payload (sensor/switch)
- Update discovery topic format: homeassistant/{component}/{node_id}/{entity_name}/config
- Fix entity naming: {metric}_{device} instead of descriptive names
- Separate state topics for sensors vs switches:
* Sensors: pilot/{device}/{metric} (no /state suffix)
* Switches: pilot/{device}/{metric}/state (with /state suffix)
- Add per-entity availability topics: pilot/{device}/{metric}/available
- Add publish_switch_state() function for proper switch state publishing
Discovery topic examples:
- homeassistant/sensor/asus/cpu_usage_asus/config
- homeassistant/switch/asus/shutdown_asus/config
State topic examples:
- pilot/asus/cpu_usage (sensor)
- pilot/asus/shutdown/state (switch)
This matches the Dell 5520 v1 configuration that works correctly.
