fix(helm): scale the classic chart's HPA out at the documented 60 percent CPU (#35975)
* fix(helm): scale the classic chart's HPA out at the documented 60 percent CPU

The litellm-helm chart shipped targetCPUUtilizationPercentage: 80, which is
unexamined helm create scaffold rather than a chosen number. It arrived packaged
with the stock minReplicas: 1, maxReplicas: 100, a commented-out
targetMemoryUtilizationPercentage: 80, and the boilerplate "such as Minikube"
comment, the same provenance as the 128Mi resource example this file just
corrected.

60 is the documented recommendation. The mechanism behind it is scale-up lag:
the chart's own startupProbe is failureThreshold: 30 times periodSeconds: 10, so
a replica can take up to 300 seconds to become ready, and a pod added at 80
percent utilization arrives minutes after saturation.

The memory target stays commented out on purpose. The prisma query engine's
resident memory is a high-water mark that ratchets to the pod's worst-ever write
and is never returned, so a memory-target HPA reads the largest write a pod ever
did rather than what it is doing now, and replicas ratchet up without scaling
back in.

hpa_tests.yaml carried its second suite after a YAML document separator, and
helm-unittest loads only the first document per file, so that suite never ran;
an assertion planted in it still passed. Fold it into the one live suite and add
coverage pinning the rendered CPU target, the absence of a memory metric by
default, and that overrides still take effect.

Bump the chart to 1.1.2, since rendered output changes for anyone running with
autoscaling enabled.

* fix(helm): bump litellm-helm to 1.1.3 after rebase onto 1.1.2
