refactor(ui): Migrate to use the new Button component consistently

[jjoyce0510]

Summary

In this PR, we migrate to using the standard Button component across all major surface areas of the application.
There are also a few minor copy changes, nothing particularly impactful. Please do a sanity check, but the behaviors should not be impacted by migrating these buttons.
