Add integration test for fan portfolio endpoint aggregating holdings across multiple creators

[Chucks1093]

Summary

The fan portfolio endpoint should aggregate a wallet's holdings across all creators it holds keys for. An integration test should seed holdings for multiple creators and confirm the portfolio response includes each one with correct quantities and total values.

Scope

• Seed a wallet with holdings in three different creators at different quantities
• Call the fan portfolio endpoint for that wallet
• Assert all three creators appear in the response with correct quantity and total_value fields
• Assert a creator not held by the wallet does not appear in the response

Acceptance Criteria

• All three held creators present in portfolio response
• quantity and total_value correct for each creator
• Creator not held by wallet absent from response
• Response includes a grand_total field summing all total_value entries

ETA: 12 hours

Hey, I can take ownership of this integration test.

I will set up the test environment by seeding a wallet with holdings for three distinct creators, leaving one unheld creator as a control. I will then write assertions to ensure the endpoint correctly returns the quantity and total_value for the held creators, completely excludes the control creator, and accurately calculates the grand_total field across all holdings.

Let me know if I am good to get started and open a PR.
