Design UI for mailbox setup: pairing mailbox app with briar
The Mailbox app can provide mailbox functionality to one Briar app to receive messages when it doesn't have an internet connection. There needs to be some sort of setup flow for the new app.
Possible flow:
- onboarding
- This is a mailbox for briar
- Navigate to X in briar to use it
- press 'start' when ready
- progress screen while we set up tor and connect to it
- show single-use setup token to be entered into briar app
- provide option to generate a new setup token (note that this can be needed even after setup appears to have completed)
- show some sort of success/status screen when setup was complete (aka briar could connect and pair mailbox)
