Description of problem:

The aggregated scorecard widgets are hidden from the homepage under the following conditions instead of displaying a fallback state:

1. The user does not own any entities and is not part of a group that owns entities
2. Entities exist, but values/statuses cannot be retrieved due to credential errors or threshold failures.

Steps to Reproduce

1. Add an Aggregated Scorecard widget to the homepage.
2. Trigger one of the following scenarios:
   1. Scenario A: Log in as a user who owns no entities (and belongs to no entity-owning groups).
   2. Scenario B: Provide invalid credentials for a metric provider to trigger a fetching error.
3. Observe the homepage.

Actual results:

• The aggregated cards disappear entirely from the homepage layout.

Expected results:

• The cards should remain visible on the homepage to maintain layout consistency. They should display a greyed-out chart and the empty state message: "Metrics to aggregate do not exist."

Reproducibility (Always/Intermittent/Only Once):

• Always
