fix: skip aggregate computation for unused commodities
When a multi-commodity flex_context includes a commodity (e.g., heat)
but no devices exist for that commodity, the sum() of an empty list
returns integer 0 instead of a pandas Series. This caused AttributeError
when calling .round() on the result later in compute().
Fixed by checking if any devices contribute to the commodity before
attempting to aggregate. If no devices exist for a commodity, skip
creating an aggregate schedule for it.
