feat: Add mapping completion in curations

[LautaroPetaccio]

This PR adds the is_mapping_complete property to the returned collections. This property is set as true if:

• There are items in the collection that don't have item curations done when the item had mappings.
• There are no items in the collection.
  The item curations now have a property that contains information about if the mapping was complete when the curation was created or updated, that occurs when the item is published or changes over it are pushed, meaning that the item was published with the mapping changes.
