Check if the item synced against the item content hash in the catalyst and not in the subgraph

We will need to check against the catalyst and not against the subgraph if the item has the same content hash or not in order to display the green orb.

No files or tests are named. Start by locating the green-orb sync-status logic and tracing where the item content hash is read from the subgraph and the catalyst; done means the orb reflects the catalyst hash comparison rather than the subgraph value.
