FIX(api): correct WorkloadHostFixedResource field access in _enrich_host_data

Previous code accessed resource.resource_type and resource.quantity which
never existed on WorkloadHostFixedResource. The correct fields are type,
model, manufacturer and physical_address, matching the model definition
and DB schema since the initial migration.

Bug introduced  in 1731e2c.
