fix: wire memory-agent-oidc secret + ornith:35b in K8s deployment

- LLM_ENDPOINT points to api.riotpiao.com (not in-cluster reasoning-predictor)
- LLM_MODEL=ornith:35b
- Authentik creds from memory-agent-oidc secret (CLIENT_ID, CLIENT_SECRET, ISSUER, TOKEN_URL)
- Removed stale poimen-memory-auth secretRef
- Removed stale poimen-memory-secrets secretRef (MEM_API_KEY still from it)
- command: ["/app/mem"] present
