Helm App Upgrade: Add support for new label on ClusterRepo to help when identifying source repository for updates

[nwmac]

EPIC: #11465

Backend: rancher/rancher#45997

Goal:

In the UI code that tries to find the correct chart to use when suggesting an upgrade to an app for a user, we should use the ner label added by the backend team - this will help to avoid the situation where we show an upgrade from a different chart repository to the one the app was installed from.

This should be a case of updating matchingChart here - https://github.com/rancher/dashboard/blob/master/shell/models/catalog.cattle.io.app.js#L50

If we do NOT have the annotations, then we should look for the predered repo name from the new label (catalog.cattle.io/cluster-repo-name), if it is there, we use that and we use a prefered repo type of cluster.
