Sensor Name Updates and Corrections

@santiagozky has identified and corrected inaccuracies in the following sensor data:

• totalGridPower
• totalLoadPower
• totalPvgenPower

To provide more clarity and consistency, the sensor names have been updated as follows:

• gridLoadPower
• solarLoadPower
• homeLoadPower
• exportPower

Important Note: While both the old and new sensor names are currently supported in your configuration.yaml under resources, it is recommended to update your configuration to use the new names.
