      When a legacy timeseries collection creation is partially rolled back, the buckets collection may persist without its corresponding view.

      The createCollection code path does not handle this case when viewless timeseries is enabled, proceeding to create a viewless collection at the main namespace. This leaves two conflicting timeseries collections coexisting, breaking FCV upgrade.

      The fix is to ensure that when a buckets collection exists without a view, the view is always created to repair the legacy timeseries, regardless of whether viewless timeseries is enabled.
