Wrap overflowing job status content

This improves the displayable content in the bottom left job panel (no Bugzilla bug posted).

The latest state of the front end doesn't wrap a lot of the new (longer) job status data recently added. This results in a horizontal scrollbar, which consumes space in an already limited, fixed container.

This change wraps any non-label line data. The [MDN spec](https://developer.mozilla.org/en-US/docs/Web/CSS/word-wrap) says that `overflow-wrap` is the current draft, but at present that property does not work with this value. So we will use the alternate `word-wrap` for now.

Here's the before and after:
