[Connect] Add ability to specify arbitrary demo accounts in example a…

…pp (#4048) ## Summary Adds the ability specify arbitrary demo / test accounts in the Connect example app. Primary use case is so we can test with different accounts internally during bug-bashing, but also useful for testing onboarding since we need to create new accounts with empty data to test it properly. ## Motivation https://jira.corp.stripe.com/browse/MXMOBILE-2793 ## Testing https://github.com/user-attachments/assets/6ad28c68-dd1b-4025-90d2-798cf2d31ec4
