[Bug] Fix issue with build order lines table (#8376)

* Revert change to BuildItem API

- Requires "allocations" for build output table
- Probably can refactor this later

* Bug fix for BuildOutputTable in PUI

- Correct calculation for "fully allocated"

* Adjust annotations for serializer

* Bump API version
