chore(argocd): delete the azhi-riotpiao Application

The Application pointed at github.com/ToyoGlobal/azhi-infra, branch
feat/azi-riotpiao-cnpg, path k8s/overlays/azi-riotpiao. It never reconciled:
status stayed Unknown because the source repository could not be read, and the
destination namespace azi-riotpiao was never created. ArgoCD reported it as an
OutOfSync managed resource of homelab-root with nothing behind it.

Also drops the ToyoGlobal URL from the AppProject allowlist. No manifest from
that repository is referenced any more, so the allowlist entry is dead weight.

Not touched here, because it is not in git: Secret azhi-infra-github in
namespace argocd holds the read-only GitHub credential for that repository.
Delete it separately once no other Application needs the repo.

The live Application object was deleted by hand. Until this commit reaches
main, the next homelab-root sync recreates it, because main still declares it.
