Add integration test for the leaderboard endpoint returning creators sorted by holder count descending

[Chucks1093]

Summary

The leaderboard endpoint should return creators ordered by holder count descending. An integration test should seed creators with different holder counts and confirm the sort order is correct and stable when two creators share the same count.

Scope

• Seed three creators with holder counts 50, 20, and 50
• Call the leaderboard endpoint
• Assert the two creators with 50 holders appear before the creator with 20
• Assert the tie between the two creators with 50 holders is broken by creator address alphabetically
• Assert the response includes rank, creator, holder_count, and current_price fields

Acceptance Criteria

• Creators sorted descending by holder count
• Tie broken alphabetically by creator address
• All four required fields present in each entry
• Creator with 20 holders ranked last

ETA: 12 hours
