fix(llm-serving): ornith 504 on cold start

Two bugs. Kong timeouts were on the Ingress; it reads them from the Service, so
its 60s default applied. Moved to the isvc, which KServe propagates.

Probes ran 'ollama list' — models on disk, not in VRAM — so the pod went Ready
before it could serve. Now 'ollama ps', and both models are warmed at startup.
