Do not use workspace-resolved AuthSecret for backup jobs.

A workspace owner with the standard namespace edit role can create a DevWorkspaceOperatorConfig in the workspace namespace and set controller.devfile.io/devworkspace-config to it. The backup path then accepts its BackupCronJob.Registry.AuthSecret, reads that-named Secret from the operator namespace, and copies it into the workspace namespace.

Use the global configuration for registry-secret selection while retaining the workspace-resolved configuration for other backup settings.

Suggested fix 
-	registryAuthSecret, err := secrets.HandleRegistryAuthSecret(ctx, r.Client, workspace, config, r.Scheme, log)
+	registryAuthSecret, err := secrets.HandleRegistryAuthSecret(ctx, r.Client, workspace, wkspConfig.GetGlobalConfig(), r.Scheme, log)

Update the registry-secret selection in createBackupJob to use
wkspConfig.GetGlobalConfig() when calling HandleRegistryAuthSecret, while
retaining the workspace-resolved config for all other backup settings.

Could we source the operator-namespace authSecret from GetGlobalConfig() in this shared helper? If I’m reading the flow correctly, namespace editors can create a DWOC that names an operator-namespace Secret, which then gets copied into their namespace. Restore appears to allow this already, and this PR extends it to periodic backups.

@rohanKanojia Yes. HandleRegistryAuthSecret is the better place to enforce this boundary. My caller-only suggestion would protect backups but leave restore exposed.

The helper currently uses the caller’s AuthSecret to select a Secret from the operator namespace. Both backup and restore pass workspace-resolved configuration.

Keep the workspace-namespace Secret lookup first. If that Secret is absent, select the operator-namespace Secret only from GetGlobalConfig():

// Import pkg/config as wkspConfig.
globalConfig := wkspConfig.GetGlobalConfig()
authSecretName := ""
if globalConfig != nil &&
	globalConfig.Workspace != nil &&
	globalConfig.Workspace.BackupCronJob != nil &&
	globalConfig.Workspace.BackupCronJob.Registry != nil {
	authSecretName = globalConfig.Workspace.BackupCronJob.Registry.AuthSecret
}

Use this instead of the current authSecretName assignment. If the global AuthSecret is empty, continue without authentication. Do not fall back to the workspace-resolved AuthSecret.

Retain the workspace-resolved configuration for scheduling and other backup settings. This limits the change to the cross-namespace Secret selection.

Regression coverage should check that:

  • A workspace DWOC cannot select an arbitrary operator-namespace Secret.
  • The globally configured Secret remains available.
  • An existing workspace-namespace Secret retains precedence.

The finding remains open until the shared-helper change is verified.
