Remove `workflow-aggregator` dependency, at least in `compile` scope. For `test` scope, could keep it, or replace with a more selective list.
Remove the common deps, have the needful in the REST API, and then rely on that that to supply libraries for the UI
Declare `workflow-job` dep in `pipeline-rest-api` POM; optionally declare it in `pipeline-stage-view` POM
<description> fields need to be provided for the separate plugins, so the wiki is not used as a source for the description (since REST API and stage view share hosting and wiki)
Improvement
Minor
