Make tags and report suite filtering available for subclassifications

Description - Where a subclassification is already created as part of copying a report suite, it is currently not possible to identify which report suite the subclassification is attached to. Tags on subclassifications do not appear in the left rail of the classification sets UI, and filtering by report suite does not return subclassifications.

Why is this feature important to you - Where there are multiple report suites that have similar classification requirements, it is difficult to identify which one has been most recently updated with the latest classification file.

How would you like the feature to work - I would like to be able to use the report suite filters or tag filters available in the classification sets UI to filter subclassifications

Current Behaviour - subclassifications cannot be easily identified or filtered by report suite or Tags
