Returns the connection's API consumption over the last 24 hours, broken down by sync when the backend supports it.

Not all integrations support usage reporting.

• callsLast24h is null when the backend does not expose a usage count.
• reportsSyncStats is false, and bySync is empty, when the backend reports a total but cannot attribute calls to individual syncs.

When per-sync stats are available, each entry in bySync carries a categories breakdown. Category keys and labels are integration-specific. For example, Salesforce reports rest and bulk categories (collapsing Bulk API v1 and v2 into a single bulk bucket), while another integration may report an entirely different set or none at all. Treat key as an opaque, backend-defined identifier and use label for display; do not assume a fixed vocabulary across connection types.
