fix(deploy): remove broken init container, document registry push workaround

The Helm init container used /bin/RunProdServer which doesn't exist in IHP's
Nix Docker image (binary is at a Nix store path). Additionally, IHP v1.5's
RunProdServer starts the server after migrating — it never exits — so init
containers are the wrong pattern. IHP applies schema changes on startup.

Changes:
- Remove initContainers block from deployment.yaml entirely
- Set runMigrations: false as default in values.yaml
- Update RUNBOOK.md with correct skopeo push procedure (pre-fetch bearer token
  to work around Gitea's misconfigured token realm URL: port 80 vs actual 32166)
- Add note that the Nix image has no /bin/sh or /bin/RunProdServer wrapper

k3s registry auth: credentials added to /etc/rancher/k3s/registries.yaml and
iptables DNAT rule added on Railiance01 (92.205.130.254:80 → 32166) so the
ACME token realm redirect works. hub.coulomb.social DNS A record still needed.

+- `skopeo` is in the Nix profile but not on PATH — use the full store path above.
+- The IHP Nix Docker image has NO `/bin/RunProdServer` symlink. The binary lives at

+  Use `kubectl exec deploy/inter-hub -- /nix/store/*-inter-hub/bin/RunProdServer <cmd>`
+  if a shell is not available (the Nix image has no `/bin/sh`).
