Fix remote object read-only + remove relations (#4921)

- Set `readOnly` boolean in table row context. Preventing updates and
deletion
- Show page is null for remote objects. No need for complicated design
since this is temporary?
- Relation creations are now behind a feature flag for remote objects
- Refetch objects and views after syncing objects
