Add Gateway API HTTPRoute support for Django service

Adds an optional HTTPRoute resource (Gateway API v1) as an alternative to the existing Ingress for exposing the Django service. This aligns with the Kubernetes ecosystem's move toward the Gateway API as the successor to Ingress.

Changes

• templates/django-httproute.yaml : New template gated by django.httpRoute.enabled.
• values.yaml : Added django.httpRoute section (enabled: false by default) with annotations and parentRefs fields.
• values.schema.json : Schema definition for the new django.httpRoute object.

Usage

django:
  httpRoute:
    enabled: true
    annotations: {}
    parentRefs:
    - name: my-gateway
      namespace: default

Notes

• Disabled by default — no impact on existing deployments.
• Can be used alongside or instead of the existing Ingress resource.
• parentRefs entries default group to gateway.networking.k8s.io and kind to Gateway; only name is required.
