fix(knowledge): repoint Ollama at edge1 + flip README to LIVE (Sprint E B7)

Two changes after the Phase 2.4 deploy went live at
https://knowledge.iamworkin.lan:

1. **Ollama URL flip**: from BLUEJAY-WS (10.0.56.20:11434) to edge1 Pi 5
   (10.0.57.17:11434). Honors the cluster-clean architecture from
   bluejay-infra@0f9d56e ("Workstation is private dev hardware and should
   not be in the cluster path"). Query-time embeddings (~ms per query)
   are fast enough on edge1; bulk index rebuilds (Phase 2.5+) will need a
   separate ingestion lane that can opt into the workstation GPU when
   present. ArgoCD picks up the env-var change and rolls the pod
   automatically — no image rebuild needed.

2. **README LIVE status**: flip the staged-not-yet-applied banner to
   LIVE 2026-04-27. Pod running, certificate issued, PVC bound,
   /healthz 200, /api/v1/editions [] (initial-deploy state). Phase 2.5+
   admin UI handles bulk population.

-imported AND DNS record provisioned before `git push`.
