Phase-6: repoint Flux source to in-cluster Gitea

Cut the GitOps source over from the bootstrap host-Gitea
(http://192.168.2.103:3000) to the now-healthy in-cluster Gitea at
https://gitea.home.keithjackson.dev. Public repo, LE-prod wildcard
cert publicly trusted, resolved in-cluster via coredns->Gateway, so
no secretRef/caCert needed. Bootstrap host-Gitea retained (stopped)
as a recovery path.
