Bug 32634: Add 'page-section' to various pages

This patch adds a "page-section" container div around the main section
of various pages which lack it.

This patch contains indentation changes, so please ignore whitespace
when looking at the diff.

Apply the patch and view the following pages to confirm that the main
content is contained in a white box:

- Locate a patron who has one or more account transactions.
  - Go to the Accounting tab -> Transactions. Click "Details" on one of
      the lines.
    - The "Details of debit" and "History" sections should be wrapped in
      .page-section.
- Go to Tools -> Patron card creator -> Manage -> Batches
  - If there is not a list of batches you will need to create at least
    one to see the page-section container.
- Go to Reports -> View dictionary.
  - If necessary, add a definition.
  - The "Current terms" table should be wrapped in .page-section.
- Go to Lists and view the contents of a list with one or more titles on
  it. The table of titles should be wrapped in .page-section.
- Go to Circulation -> Upload offline circulation file (.koc)
  - Upload a .koc file and click the "Add to offline circulation queue."
  - On the confirmation page the "Your file was uploaded" message should
    be wrapped in .page-section.
  - Click "View pending offline circulation actions"
    - The list of pending actions should be wrapped in .page-section
