Card Elo on card pages doesn't match latest Elo on the Elo graph

[lborthwein]

Describe the bug
The elo value used for sorting cards and that displays when you click into a specific card under the card image is very different from the elo reported on the historical elo graph for that card. Many cards that have interesting historical elo data show as 1200 (default) elo on the card's page and others have wildly different values showing in the two locations. This makes it hard to use the elo sorting function effectively.

To Reproduce
https://cubecobra.com/tool/card/85c60177-8b71-4e24-87e7-395d5e4f93ff?tab=1 look at this card, for example. Its elo on the card page is showing as 904 whereas the most recent elo over time value is 1271

Expected behavior
I'd expect the sorting value to equal the value under the card's name (as it does) but for those to correspond to the most recent historical value of the elo, which is presumably most accurate
