Layout of expanded details content

[jvine]

For the label/value pairs in the expanded detail panels, the spacing is too loose and affects readability.

• This seems to work for the <dt> / <dd> pairs:
  <dt class="col-3 offset-1 col-md-2 offset-md-2">
<dd class="col-8">

• For "View in SearchWorks" and other standalone links or text:
  <div class="col-11 offset-1 col-md-11 offset-md-2">

• REMOVE .justify-content-center from the containing rows for both of the above.
