anubis: run the image under a localhost/ alias tag

On this host's podman 5.7 quadlet path, a registry-prefixed Image ref
fails to resolve from local storage at container create time even when
the image is present ('image not known'); the identical argv works from
a shell or transient unit. Verified live: an identical unit with
Image=localhost/techarohq/anubis:v1.13.0 starts immediately. The deploy
handler now tags the alias after the guarded pull; upgrades re-tag
after pulling the new tag.
