Adding new items/categories reverts selectedPack to first one

I believe it has to do with the way the update method rewrites the cache in the create methods of the service files. Because it's reading/writing the entire PACKS_QUERY, this might be changing the selectedPackId variable which in turn triggers the selectedPack apollo query since it has a reactive variable.

Ideally, would figure out more efficient way to update cache. Short-term, may need to rework selectedPack apollo query in closet page to only fire after specific events are triggered.
