Overview

I found that the pointer profiles could go out of sync if they were reserialized without the inspector open. This change ensures that

1. The pointer itself is the source of truth if there's any serialization present
2. If no serialization is present in the pointer, default to either the global default (if initializing the field for the first time) or to whatever's in the profile serialization
3. If the profile is changed through the inspector, immediately sync the result back to the prefab and save
