devnet-8: serve all tooling on plataberget.ethpandaops.io alias hosts

[barnabasbusa]

Summary

Follow-up to #65: adds the plataberget.ethpandaops.io alias host to the remaining 15 tools (dora, beacon, faucet, forkmon, forky, assertoor, spamoor, tracoor, syncoor, buildoor, checkpoint-sync, auth, faucet-agents, homepage apex) so every plataberget hostname is served directly by the devnet-8 ingresses.

This lets us remove the plataberget-alias Cloudflare worker entirely: the Workers free tier is 100k req/day and today's quota is already exhausted (99.6k by 10:30 UTC, mostly pre-#65 rpc traffic) — once the cap is hit, all worker-routed hosts fail until midnight UTC.

Rollout

1. Merge this → Argo syncs the ingresses (verified pattern works: devnet-8: serve rpc on rpc.plataberget.ethpandaops.io alias host #65 / rpc)
2. Then remove the worker routes + script in ethPandaOps terraform (PR to follow) — the DNS records and cert pack stay as-is

Notes

• values.yaml files are ansible-generated — deliberate one-off; a future gen_kubernetes_config run for devnet-8 would drop the alias hosts unless re-applied.
• auth.plataberget.ethpandaops.io/auth/* will need a matching Cloudflare Access application (going in the terraform PR) — until then the alias auth host's /auth/* is not Access-protected, unlike its glamsterdam counterpart.

[redpandabot]

Adds plataberget.ethpandaops.io alias hosts to the ingress config of the remaining 15 devnet-8 tools. Purely additive YAML that mirrors the verified #65 snapshot pattern; the one file with an explicit tls block (checkpointz) was correctly extended to include the alias host. No issues found.
