Subject: [PATCH] refactor(templates): the last inline styles that Bootstrap
 covers

- The VM list's power forms (style="display:inline") are d-inline.
- The fields scripts show and hide are d-none, and the scripts add and
  remove that class instead of calling jQuery's show() and hide(),
  which could not undo it: the custom memory boxes of the Resize tab,
  the ISO upload's error message and the clone dialog's metadata row.
- The please-wait dialog's full bar is w-100.
- The create-VM pages' own 56rem width (.create-vm) goes: pages stop
  at 960px now, about the same.
- static/css/font-awesome.min.css goes: no page loaded it, no element
  used its classes and its fonts were never in the repository.
