Class ApolloGetListsAction

Lists the Apollo labels — lists and tags — with each one's kind ('accounts' | 'contacts') and cached member count.

This is the first call in any list workflow, because every other action here addresses lists by exact name and this is what tells you the names. Read-only.

Inputs:

• CompanyID (optional) resolve the key from this company's Apollo credential instead of APOLLO_API_KEY

Outputs:

• Lists array of { id, name, kind, cachedCount, createdAt, updatedAt }
• Count number of labels
• KeySource 'credential' | 'environment' — which path supplied the key
