Summary
This pull request introduces a feature that allows for manual overriding of the calculated AC consumption values on a per-phase basis.
Description
A new setting, /Settings/SystemSetup/HasUserConsumptionCalc, has been added. When this setting is enabled, dbus-systemcalc will no longer use its own calculations for AC consumption on the output.
Instead, it will read the power values directly from the following new settings paths:
The values from these paths are then used to populate the /Ac/Consumption/[L1-L3]/Power and /Ac/ConsumptionOnOutput/[L1-L3]/Power D-Bus paths.
This functionality is designed for specific scenarios where AC loads cannot be measured automatically by the system and need to be accounted for manually. If HasUserConsumptionCalc is disabled, the system reverts to its standard calculation method.

This also helps when user has another one VM meter for loads specifically and reroutes values to these settings in order to get proper AC Load calculations
