[Connect SDK] UI for Connect SDK Example App

[simond-stripe]

Summary

This adds the UI for the Connect SDK example app. It's mirrored off of the other example apps in this repo (ex. PaymentSheetExample and FinancialConnectionsExample).

The app has UI for both components in the Connect SDK: AccountOnboarding and Payouts. Both are currently Beta and more can be added easily in the UI as the Connect SDK evolves.

Motivation

This is meant to:

1. show off the capabilities of the SDK and
2. demonstrate a canonical integration of the SDK to integrators

Testing

• Added tests
• Modified tests
• Manually verified

Risky Change

This is considered a risky change because it adjusts the sample app build.gradle, please review carefully.
We've seen issues in the past which resulted in failed builds for merchants. Please make sure the build.gradle change is intended.

By adding the label accept-risky-change to this PR, I acknowledge that I'm changing an example app and have verified that the SDK remains in a shippable state.

Can you make these string resources?

[tjclawson-stripe]

Can you also make these resources?

Agree about moving some things to res, looks good on my end! 👍

The base branch was changed.
