suggestion (bug_risk): Detached call with unawaited means the function returns before fetch completes

Remove unawaited and await the fold result directly so this function’s Future represents the network call. Alternatively, adjust the caller to not assume _handleFetchWorkspaceSubscriptionInfo covers the fetch lifecycle.
