[Request] Include rarity/slots in store page

[Serity]

As a new player who doesn't have access to creating extra slots on equipment yet, it'd be useful to know how many slots the items in the store have before purchasing them, without having to first cross-reference the Wiki or pulling the store open on my phone.

The information seems to already be sent from the API, but is unused?
