Run a single Gitea container on the host (bootstrap/gitea/), outside the cluster,
while the cluster is built; Flux pulls this repo from it over the k3s-dev NAT
gateway (http://10.73.0.1:3000/Home-Network/home-network-k3s-impl.git, public repo
=> no creds, NAT-only). Wired the flux-system GitRepository url in clusters/dev.
Migrates to in-cluster Gitea in Phase 6. Pins confirmed. Author-only; gate PASS.
