Brave-browser: Sync - UX improvement - Users need a confirmation message after first successful sync of two devices

[alexwykoff]

Description

After numerous usability tests, a consistent pattern of confusion emerged where showing a list of devices on sync chain was insufficient for conveying success to the users. This confusion led to operational errors on the part of the user.

Steps to Reproduce

This is not a programmatic error, so to reproduce one would need to conduct usability tests with new users.

Actual result:

Users exhibited confusion during the success state of the Sync flow.

Expected result:

For first-time Sync users, they should leave the Sync settings page and continue operation of the browser.

Reproduces how often:

This is a fairly regular occurrence for new or non-technical users.
