Add integration test for creator list returning stable ordering for creators with identical sort values

[Chucks1093]

Summary

When two creators have the same value for the sort field (e.g. identical prices), the list must return them in a stable and consistent order across paginated pages. An integration test should confirm no creator is duplicated or skipped when sort values are tied.

Scope

• Seed three creators with identical current prices
• Fetch all pages of the creator list sorted by price
• Assert all three creators appear exactly once across the combined pages
• Assert the order is consistent between two identical requests

Acceptance Criteria

• All creators with tied sort values appear exactly once
• Order is consistent across repeated requests
• No creator skipped or duplicated across pagination pages

ETA: 12 hours
