Phase 1: file one Paperclip job from a script

Add scripts/paperclip-roundtrip.sh. It files one Paperclip issue and prints
the returned id and identifier. The key comes from the environment, then from
environment.d. The script never prints the key.

Fix the runbook: the create route is POST /api/companies/{companyId}/issues.
The old POST /api/issues route returns 404.

Record the first filed job: AUD-55 (d58891ce-9934-4710-9bba-d37974251ed9).
