fix(ci): push image to Forgejo registry and update GitOps repo over HTTPS

The GitOps step relied on GITEOPS_REPO/GITEOPS_SSH_KEY secrets that were
never configured, and the registry login used a REGISTRY_HOSTPORT secret
that doesn't match this repo's actual registry setup. Switch to the
Forgejo registry directly and push the GitOps update over HTTPS with a
token, matching how other services in this org already deploy.
