A-316: the assigner's candidate gains added, the version and parts the want it would write carries

The state candidates' value (CandidatesByProposalNodeValue) gains `added`, by module name, each an AddedModule
with `version` and `parts` in the want's own forms. It is a copy of the two properties of the seat mesh-wants'
state wants, because the seat-definition format cannot reuse another repository's seat's forms (includes take only
parts/ of the same repository, and a part holds no state value); a fixture holds both to the want's wire.
Regenerated with seatgen. The node names the first round-2 pass left in fixtures lines equal to base lines are
role names now, the generated tests with them.

Builds: design 47 G A-316 (corrected, hq #594), §626
