Part of the bigger "Account Settings" project - https://github.com/Expensify/Expensify/issues/182122

This is one of the last pieces of this project!!

Goals for this issue:

• Hook up "Set as default" button in Contact Method Details page
• Make sure the command works & all offline UX for this flow is perfecto 👍
