fix: display correct OCIRepository sources for HelmReleases in applications page

[Elgarni]

Closes

What changed?

🛑 In Applications page, when the source is OCIRepository, it displays incorrect info:

And after clicking on the app it's obviously showing not found as the info are not correct:

✅ With this change, it's fixed:

For reference, these are the objects spec:

apiVersion: source.toolkit.fluxcd.io/v1
kind: OCIRepository
metadata:
  labels:
    app.kubernetes.io/managed-by: flux
  name: gha-runner-scale-set-controller
  namespace: github-actions-operator
spec:
  interval: 1h0m0s
  ref:
    tag: 0.10.1
  url: oci://ghcr.io/actions/actions-runner-controller-charts/gha-runner-scale-set-controller
---
apiVersion: helm.toolkit.fluxcd.io/v2
kind: HelmRelease
metadata:
  labels:
    app.kubernetes.io/managed-by: flux
  name: github-actions-operator
  namespace: github-actions-operator
spec:
  chartRef:
    kind: OCIRepository
    name: gha-runner-scale-set-controller
  interval: 1h0m0s
  releaseName: github-actions-operator

Why was this change made?
Explained above ^

How was this change implemented?

In the frontend, HelmRelease.spec.chart is handled, but HelmRelease.spec.chartRef is not (which is the case when deploying from OCI Repository)

For more info check Flux docs here https://fluxcd.io/flux/components/helm/helmreleases/#chart-reference

How did you validate the change?

• checked all sources for HelmRelease and ensured all is working
• no breaking changes or refactoring for existing code. Added only missing support for chartRef
