fix: retrieve all the wallets in the account

[mominafiz]

Description

The default page size of 50 records may miss the wallet with funds, resulting in an 'Insufficient funds' error. This is an edge case as the error is only seen when a user has selected all the wallets when creating an API key.

Currently, Coinbase lists around 70 wallets and when increasing the page size to 250 the error is resolved. However, this is valid until the number of wallets is more than the maximum page size.
