Mailbox activate/deactivate button needs a confirmation prompt or message

[MattApril]

The Yes/No button in the "Active" column of /mailbox needs one of the following UX enhancements:

• a confirmation prompt before changing the mailbox state, or
• a success message displayed after the state has been changed

As is, it's very easy to accidentally activate or deactivate a mailbox without even noticing.

I may be able to put in a pull request for this, but I am very unfamiliar with this app. Which option would you prefer, and is there any similar functionality that exists in the app elsewhere that I can reference (e.g. components for a toast message or confirmation dialog)?
