Summary

• use the host hostname as the Ansible inventory alias so Ansible stdout reports hostnames instead of CT-Ops host ids
• keep CT-Ops host ids in the API response while parsing Ansible JSON callback results by hostname
• add Ansible API contract coverage for hostname-based inventory aliases

Fixes #1316

Tests

• python3 -m unittest discover tests (from apps/ansible-api)

Notes

• Tried running the web unit test command, but pnpm is not available on this shell's PATH.
