feat(ui): add quota overview (#6602)

Add UI to the quota feature to see what quotas applies to you and if you're exceeding any quota, it's designed to be a general size overview although it's exclusively filled with quota features for now. There's also no UI to see what item is actually taking in the most size. Purely an quota overview.
