align kserve web appLICATION helm parity

[danish9039]

Follow-up to #3393.

The KServe Models Web App manifests were renamed to kserve-models-web-application, but the downstream Helm chart and Helm-vs-Kustomize comparison were still using the older kserve-models-web-app identity and stale chart defaults.

This PR updates the Helm chart to match the synced manifests, adds the missing inferencegraphs RBAC permissions, and switches the parity checks to chart-local CI values for the base and Kubeflow scenarios.

Verification:

• bash -n tests/helm_kustomize_compare.sh
• tests/helm_kustomize_compare.sh kserve-models-web-app base
• tests/helm_kustomize_compare.sh kserve-models-web-app kubeflow

Pull request overview

This PR aligns the KServe Models Web App Helm chart with the synced upstream manifests, following the upstream rename from kserve-models-web-app to kserve-models-web-application. The changes include:

1. Helm Chart Alignment: Updated the chart name, labels, and image tag to match the upstream restructured manifests
2. RBAC Permissions: Added missing inferencegraphs and inferencegraphs/status permissions to ClusterRole
3. Test Infrastructure: Created chart-local CI values files and updated comparison logic to use them, ensuring proper parity checks between Helm and Kustomize for both base and Kubeflow scenarios

Changes:

• Updated Helm Chart.yaml to use new chart name and appVersion 0.16.1
• Updated component labels in Helm templates to match upstream naming convention
• Added missing inferencegraphs RBAC permissions to align with upstream
• Created ci/base-values.yaml and ci/kubeflow-values.yaml for scenario-specific configurations
• Updated helm_kustomize_compare.sh to use chart-local CI values files instead of inline arguments
• Updated helm_kustomize_compare.py to remove special-case AuthorizationPolicy expectations for base scenario
