"""gitea — parity port of recipe-info/gitea/tests/git_push.py (phase gtea).

SOURCE: references/recipe-maintainer/recipe-info/gitea/tests/git_push.py

Original: create repo via API → clone → commit → push over HTTPS → verify commit via API → delete.
cc-ci port: same flow, adapted to the per-run domain and the harness admin creds from ops.py.
Non-vacuous: a broken SCM fails the push or the API verification.
