Bug 39441: Some staff interface templates have div.container instead of div.container-fluid

This patch updates a few templates so that div.container is replaced
with div.container-fluid. div.container gives us a fixed maximum width
that isn't consistent the rest of Koha.

To test, apply the patch and go to the staff interface.

- Perform a catalog search which will return multiple results.
- In the search results, check multiple results and click "Add to cart."
- Click the cart icon in the top menu to trigger the cart popup.
- The contents of the cart popup should fill the whole width of the
  window.
- The other instances of this are less noticeable because of how the
  pages work. These changes are more about consistency:
  - The OPAC place hold page
  - The club enrollment process (both in the OPAC and the staff
    interface)
  - As long as these interactions work correctly all is good.
