{{/*
Common resource rendering helpers for kserve charts.
These helpers encapsulate the logic for loading, patching, and rendering common resources.

{{/*
Render a simple resource by loading a base file and optionally replacing namespace.

Parameters (dict):
  - baseFile: string - Path to the base resource file (e.g., "files/common/certmanager.yaml")
  - replaceNamespace: boolean - Whether to replace namespace in the resource
  - context: . - The root context for accessing .Release, .Files, etc.

Example usage:
{{- include "kserve-common.renderSimpleResource" (dict
  "baseFile" "files/common/certmanager.yaml"
  "replaceNamespace" true
  "context" .) -}}

{{/*
Render a patched resource by loading base and patch files, optionally replacing namespace,
then merging them using deep merge.

Parameters (dict):
  - baseFile: string - Path to the base resource file

  - context: . - The root context for accessing .Release, .Files, .Values, etc.

Example usage:
