Panda Status v1.0.3 Lacks Home Assistant Integration Documentation and Displays Incorrect Version (v2.0.0)

## Problem Description

After updating the BIQU Panda Status to firmware version **v1.0.3**, the device incorrectly reports the firmware version as **v2.0.0** in the interface.

Additionally, there is currently no official documentation or setup guide explaining how to integrate or connect the Panda Status with Home Assistant. I was unable to find any instructions covering:

- MQTT configuration
- Home Assistant entity setup
- Required integrations
- Network or API configuration
- Example YAML or auto-discovery support
- Firmware requirements or compatibility notes

This makes Home Assistant integration difficult to configure or validate for users attempting to use Panda Status within an existing smart home setup.

## Expected Behavior

- Firmware v1.0.3 should correctly display as **v1.0.3**
- Official documentation should include clear instructions for connecting Panda Status to Home Assistant

## Actual Behavior

- Firmware displays as **v2.0.0**
- No discoverable Home Assistant integration/setup documentation exists for Panda Status

## Requested Improvements

- Fix incorrect firmware version reporting
- Add official Home Assistant integration documentation
- Provide MQTT topic documentation and setup examples
- Clarify supported Home Assistant features and requirements
