Remove the git clone container's anonymous volume with it (closes #215)

The pinned `alpine/git` image declares a volume at `/git`, so every clone container got an anonymous volume, and the container was removed without its volumes, leaving one volume behind per deploy. The clone container is now removed together with its volumes, whether the clone succeeds, fails or is cancelled; the removal uses a context that outlives cancellation. Tests cover success, failure and cancellation against a fake Docker API, and a manual check against real Docker is recorded on the PR. The old app container's own anonymous volumes are still kept on redeploy, since deleting them could discard app data. Model: opus-5-5

 # Completed Steps

+- 2026-09-23: The git clone container is now removed together with its anonymous
+  volume (the `alpine/git` image declares one at `/git`), so a deploy no longer
+  leaves a Docker volume behind (#215).
 - 2026-09-23: Deployment log files are now stored under `logs/<appname>/`
  instead of `logs/<hostname>/<appname>/`, so downloads keep working after the
  upaas container is recreated; logs written under an old hostname directory are
