gui: Fix wrapping in "Shared With" / "Folders" lists. (#9438)

This change was split off from #9355 as an independent clean-up / fix.
See that PR for review discussion, testing, and screenshots.

Improve the wrapping of folder labels / device names by going back to
word-wrapping, but making sure other spans, such as the trailing comma,
do not get separated from the label span.

* Avoid adding whitespace caused by line wraps in HTML source code.

The different cases within the ng-switch block are separated by
newlines for readability, but that gets parsed as whitespace.  For
wrapping purposes, this should not happen, because then there is no
way to keep other HTML parts glued to the name / label in each list
entry.

* Simplify redundant conditional comma code.

The separating comma after a device name or folder label (all but the
last) should always stick to it.  Use the HTML comment trick to avoid
whitespace and therefore a wrapping opportunity caused by the code
formatting newline.  Thus the conditional comma only needs to be
defined once, not in each ng-switch case.

* Wrap at word boundaries and only break up words if necessary.

Use the overflow-wrap: break-word; style instead of word-break:
break-all;.  While the latter is suitable for longish paths, breaking
device names or folder labels arbitrarily within words is ugly.

This also makes the the <sup> numbers actually stay glued to their
respective neighboring words.

Include legacy CSS alias "word-wrap" in the class definition.

* Fix indentation (unrelated).
