Cost Explorer API (11/n): adopt strategy for total component attributed costs

[consideRatio]

Definition of done

• Let aws-ce-grafana-backend acquire data for the daily total costs like in Cost Explorer API (10/n): adopt strategy for total cost per hub #4784, but now grouped by AWS service components instead of hubs.
• Let aws-ce-grafana-backend combine AWS service components into categories such as object storage, home storage, and compute based on a simple map.
• A manually defined grafana dashboard should be examplified to function against the backend. This should be panel 2 in [EPIC] Support attributing costs to individual hubs automatically on Openscapes #4453 (comment).
