JP album on user profile contains non-existent cards

When expanding a user's Album on their page, the IDs for cards go sequentially from 1 -> 2009, where 2001 -> 2009 are the Worldwide Poster Girl Promo URs.
This is a problem because a) the WWPGPURs aren't available on JP to begin with,
and b) cards from the current latest card, (1387 as of writing) to 2000 are listed, even though the cards simply do not exist yet.

Solution: No longer display cards all the way down to 2009 on JP albums until the WWPGPURs become available, at which point don't display the non-existent cards in between

Start at the user-profile Album endpoint and trace how JP card IDs are selected. Compare the returned range with the latest JP card and the Worldwide Poster Girl Promo UR boundary; done means JP albums omit unavailable and non-existent cards while retaining available cards.
