Add a way to track successful/failed pauses

[LeoColman]

With the Break/Pause feature, it would be interesting as an user to know how successful that pause period has been for me.

The app https://github.com/iSoron/uhabits displays habit-tracking in a beautiful way:

We can leverage that idea and include a tracker specifically for the break period, giving a bigger sense of accomplishment.

To add to the discussion, should the Pause feature get a page to itself?
If we plan to escalate the feature to include things like Tolerance breaks, a dialog is way too simple for this
