fix: Fix customerV2 index schema

[Peeja]

I don't really understand this code, I just know that Dynamo complained until Claude told me this part was wrong and unnecessary. Can anyone confirm? I couldn't run Sprue at all without this change.

What is the error? This is working for me and in tests.

The subscription is used in ListByProviderAndCustomer as the cursor value for paginating over subscriptions. I think the tests are still passing because they are not asserting on the returned values for each page.

The error looks like:

creating DynamoDB table "subscription": ValidationException: Key Schema too big.
Key Schema must at most consist of the hash and range key of a table

I think I remember seeing something like this and I was becasue I had an old "latest" dynamodb image - what version are you using? Maybe try upgrading?

I think that did it! Thanks!
