Add workflow/publish-rule/env setup, bulk publish-unpublish tests (003a/004a/003b/004b), and 422/141 handling with console output.

Ensure environment (find/create bulk_test_env) and workflow “oggy” (find/create with branches/stages) in ClassInitialize; add Test000c for environment; update Test000a/000b with find-or-create and Branches; Test002 creates five entries and assigns workflow stages; Test003a/004a/003b/004b use bulkTestEnvironmentUid, PublishWithReference, and skipWorkflowStage/approvals (003b/004b with api_version 3.2); treat 422 ErrorCode 141 as expected and log full message to console; fix UnPublish → Unpublish.
