Add integration test for activity feed pagination returning correct next cursor on first page

[Chucks1093]

Summary

The wallet activity feed supports cursor-based pagination. An integration test should confirm the first page response includes a valid next cursor that can be used to fetch the second page without duplicating or skipping events.

Scope

• Seed a wallet with more trade events than the default page size
• Fetch the first page and assert a next cursor is returned
• Use the cursor to fetch the second page and assert no event appears on both pages

Acceptance Criteria

• First page returns a valid next cursor
• Second page using the cursor contains no duplicates from the first page
• All events appear across the combined pages

ETA: 12 hours
