fix: create temporary environment for publish tests instead of skipping

The § 3.4 publish tests were pending because the fresh dynamic stack has
no environments (they're only created by Phase 5 environment tests).

Fix: before() now creates a throw-away environment when none is found,
and after() deletes it. Same self-contained pattern used by AM org stack.

Priority order:
1. Use testData.environments.development.name if Phase 5 already ran
2. Query for any existing environment
3. Create a temporary environment (scan-publish-env-XXXXX)

Verified locally: 32 passing, 0 pending, 0 failing
