Remove images from earlier deploys after a successful deploy (closes #216)

After a successful deploy, upaas now removes the app's images other than the one the running container uses and the previous one, which rollback starts. Removing an image also removes the untagged images it was built on unless another image still needs them. Images left by other stages of a multi-stage build are not tied to the app and stay. Model: opus-5-5

 - 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
