[backport v2.14.2] UI -- Resources column not displaying values in Fleet App Bundles section

[rancher-ui-project-bot]

This is a backport issue for #17563, automatically created via GitHub Actions workflow initiated by @marcelofukumoto

Original issue body:

Setup

• Rancher version: 2.15 head
• Rancher UI Extensions: None
• Browser type & version: Google Chrome Version 147.0.7727.138 (Official Build) (arm64)

Describe the bug

We are working in the Fleet section and observed that the Resources column is not displaying any values, even though the bundles and clusters are correctly marked as ready.

This behavior is inconsistent with the expected state, where resource information should be visible once the bundle is successfully deployed and the cluster is ready.

To Reproduce

1. Create or register a cluster.
2. Navigate to the Fleet section.
3. Create or add an App Bundle (e.g. from a GitRepo source).
4. Wait until the bundle status is Active and the cluster shows 1/1 Ready.
5. Open the App Bundles view.
6. Check the Resources column for the created bundle.

Result
The Resources column is empty (shows “—”) for all listed bundles, even though the bundles are active and clusters are ready.

Expected Result
The Resources column should display the corresponding deployed resources for each bundle once the cluster is ready and the deployment is complete.
